Node Geometry Editor Nodes

What to Expect

This page is a breakdown of each node available in the Node Geometry Editor. The nodes will be listed in the same order by group as they are in the tool's node list. The reason for this order is that there may be some generalities that apply to all nodes in a group and those will be listed once rather than repeating them for each node. For each node we will discuss all inputs, outputs, properties, and considerations to ensure all requirements for using a node are highlighted.

Sources

Source nodes are a requirement for any Node Geometry graph as they supply the Geometry that is needed by the GeometryOutput node for the graph to be able to build. Most of these nodes will come with multiple inputs that will set the basic properties of the Geometry, but all have exactly one output which is Geometry generated by the source node.

Each parameter that can be set for the source Geometry can either be set by connecting a node or nodes to set a specific value or it can be set in the properties of the node. If a parameter's port on the node is connected by a wire, the parameter is removed from the parameter list on the node as it is deriving its value from the connected node(s).

If there is a set of connected properties - such as size, width, height, and depth - the more specific properties take precedence over the more general properties. In other words, if values are passed to size AND width then the parameter passed to width will apply to the width of the Geometry and height and depth will take their values from size. In this way, it is normal to see values wired to both general and specific properties at the same time. If, however, there are values passed to size, width, height, and depth then the value passed to size is not used at all and is not needed.

Inputs

Input nodes consist of basic value types used to set properties on other nodes. There are a few common properties on all input nodes. Those consist of the following.

Mode allows the input to be defined as a user-defined value or a contextual value of any type. User-defined values are just as they seem, the user assigned a constant value to the node. A contextual value is derived from the closest geometry node associated with this node. Changing mode to a different value can also change the type of data the node represents. For example, a Float input can be changed to a Vector2 contextual value which will change the data type supplied by the node. Be aware of this when changing mode as it can affect connections to other nodes. Note that if mode is set to a contextual value, the node will no longer display Visible on frame, Min, Max, or Value in the node properties but will instead display Contextual value.
Contextual value assigns the source of the data for any input set to a contextual value. The sources available depend on the data type selected for the input node. For example, choosing a Int contextual value allows access to vertex IDs and choosing a Vector3 contextual value would offer vertex positions.
Visible on frame is a boolean which allows any input contained within a frame to be visible in the INPUTS list of the properties panel for a frame. Simply enable the boolean and then whenever a frame is selected - expanded or collapsed - any visible input can have its value changed directly in the frame properties panel.

Float

This input node represents a Float value rounded to four decimal places. The node contains the following properties which can be set in the properties panel.

Properties

Min provides the minimum value and if set, the node will create a slider between minimum and maximum values. For the slider to work correctly, ensure that the Min value is lower than Max value.
Max provides the maximum value and if set, the node will create a slider between minimum and maximum values. For the slider to work correctly, ensure that the Max value is higher than Min value.
Value is a user defined value that is either an input field or a combination of input field and slider if Min and Max are set. The value set in the field will be rounded to four decimal places by default.

Outputs

value is the Float value set on the node.

Int

This input node represents an integer value and contains the following properties which can be set in the properties panel.

Properties

Min provides the minimum value and if set, the node will create a slider between minimum and maximum values. For the slider to work correctly, ensure that the Min value is lower than Max value.
Max provides the maximum value and if set, the node will create a slider between minimum and maximum values. For the slider to work correctly, ensure that the Max value is higher than Min value.
Value is a user defined value that is either an input field or a combination of input field and slider if Min and Max are set. If a Float value is entered, any fractional value after the decimal will be ignored.

Outputs

value is the integer value set on the node.

Vector2

This input node represents a Vector2 value and contains the following properties which can be set in the properties panel.

Properties

Value displays the value set in the node. To change the value, click on the plus (+) icon to get the input fields for each channel. These values are rounded to three decimal places by default though the node only displays two decimal places.

Outputs

value is the Vector4 value set on the node.

Contextual

Contextual nodes consist of values derived from the closest source associated with a contextual node in the graph. The way to determine what source is referenced by a contextual value is to trace wires from the contextual value node until finding a node that has a reference that could supply the context. For contextual nodes that reference geometric values like position or normal, trace wires to the first node that references geometry, and this will be the source that is being referenced.

Tracing contextual values to their source geometry

In addition to geometric contextual values, there are other types of contextual values. One of them being LoopID which is a contextual value for the iteration of a node that loops. In this case, tracing wires to the first node that is iterable would be the source for the contextual value.

Tracing non-geometric contextual values to their source

To help in identifying what source is feeding a contextual value, the graph will highlight the node providing the source of the contextual value when selecting any contextual value as can be seen in the images above. The playground below can be used to experiment with contextual values and better understand how they reference their source.

Contextual nodes are typically an array of values determined by the components of the source such as the vertices of referenced geometry or There are a couple of common properties on all input nodes. Those consist of the following.

Mode allows the node to be defined as a user-defined value or a contextual value of any type. User-defined values are just as they seem, the user assigned a constant value to the node. A contextual value is derived from the closest geometry node associated with this node. Changing mode to a different value can also change the type of data the node represents. For example, a CollectionID contextual node can be updated to a Vector2 contextual value which will change the data type supplied by the node. Be aware of this when changing mode as it can affect connections to other nodes. Note that if mode is changed to user-defined, the node will no longer display Contextual value but will instead show Visible on frame, Min, Max, and Value in the node properties.
Contextual value assigns the source of the data for any input set to a contextual value. The sources available depend on the data type selected for the input node. For example, choosing a Int contextual value allows access to vertex IDs and choosing a Vector3 contextual value would offer vertex positions.

Logical

Logical nodes are used to branch a node graph by performing a test between two Float values. If the test between the two values meets the condition set by the node, a value of true is returned and the nodes connected to the ifTrue port are passed to the output. Otherwise, the nodes connected to the ifFalse port are passed to the output. There are common properties that are possessed by all logical nodes and are as follows.

right is an input field to be able to set a Float value for the right port manually. This is a shortcut to help reduce complexity on the graph if the test needs to be done against a constant value.
Test sets the condition for the comparison between the two values connected to the node. Any logical can be easily changed to another logical node simply by changing the Test parameter without needing to replace the node with a different logical node.
ifTrue and ifFalse ports on each logical node do not need to be connected to anything for the node to function. If a node is connected to ifTrue or ifFalse, that node will be passed when appropriate condition is met. If nothing is connected to ifTrue or ifFalse, the node will output 1.0 and 0.0 respectively. This allows for successive logical tests by testing if the previous logical test was true (1.0) or false (0.0) without the need to wire Float nodes for ifTrue and ifFalse in the graph.

These nodes are simple mathematical operations like add, subtract, min, max, or round. The nodes in this section are some of the most used nodes in any of our node graph tools. They are very straight forward, but many of the nodes in this set have features that are worth calling out specifically.

Add

This is a simple math node which adds two inputs together. This node can support Float, Int, Vector2, Vector3, and Vector4 types, though the node cannot add mixed types. The type of the node first connected to an input determines the type for the node output.

Second connect a Float to the right input of the node which will act as the scalar. This is the only math node where input types can be mixed, and these mixed input types need to be connected in one specific way. Remember, the left input can take any type and the right input can either take a matching type to multiply normally, or a Float type to be used as a scalar for the value connected to the left input.

These nodes are used to transform or convert vectors derived from geometry or user defined. As the name of the category suggests, these nodes support Vector2, Vector3, and Vector4 types.

Normalize

This function transforms the input vector into a unit vector of length 1.0. This node can support Vector2, Vector3, and Vector4 types. The type for the node connected to the input of this node determines the type for the node output.

Outputs

output is the unit vector of length 1.0 transformed from the input vector in a type that matches the input value type.

Transform

This function transforms the input geometry using either a custom Matrix or a Vector3 input for translation, rotation, and scaling. The required input for this node is the geometry input and the output will also be geometry. The rest of the inputs are optional, but if providing a Matrix input to the node, the translation, rotation, and scale inputs will be ignored as the Matrix takes precedence over the individual transform inputs.

Properties

rotation is an input field for a Vector3 value in radians to be used to set the rotation of the geometry. This property is only visible if there is no wire connected to the rotation input.
scaling is an input field for a Vector3 value to be used to set the scale of the geometry. This property is only visible if there is no wire connected to the scaling input.

Advanced

Evaluate context is used for optimization in the graph when using successive iterable nodes. If this property is set to true, each iteration in this node will also calculate all looped context feeding this node. If there are several iterable nodes connected in sequence, the calculations become exponential with every iteration of the current node calculating every iteration of the previous node back to the beginning of the chain. This can cause a spike in process time in the graph. Disabling evaluate context will prevent nodes from initiating evaluations of previous context each iteration which will greatly speed up the graph. However, since there may be a case where it is desireable to re-evaluate context with each iteration of a node, this parameter is available to the user and defaults to true. If a graph seems to be taking too long to process, check iterable nodes to see if disabling the evaluation of context will help improve performance.

VectorConverter

This node is used to either split a vector into its components or assemble components into a vector. This node has a lot of utility for introducing a change into one or more components of a vector based on the need of the user. It can also be used to swizzle components or assemble components in several ways to make up a vector. Each input will override the narrower inputs below it. For example, a Vector4 connected to the xyzw input will override any values connected to xyz, xy, zw, x, y, z, or w. The process is the same for each input so any value connected to the xy input will override any values connected to the x and y inputs.

The values provided by the outputs depend entirely on the values connected to the inputs. The node will work from the top input down and assemble a Vector4 value which can then be referenced from any of the outputs. If there is a component of the Vector4 output that was not defined in the input, the value of that component will be 0.0. This means if you only connect values to the x, y, and z inputs there will still be a Vector4 value available in the xyzw output that has 0.0 for the value of w. Since the inputs work from the top down, the VectorConverter will work with various combinations. For example, connecting values to the xy input as well as the z and w inputs will create a complete Vector4 value with no overrides. However, if connecting values to the xyz input as well as the z and w inputs will create a Vector4 of the xyz input and the w input, ignoring the value connected to the z input.

Inputs

xyzw is connected to a Vector4 value which overrides duplicate channel values lower on the node.
xyz is connected to a Vector3 value which overrides duplicate channel values lower on the node.
xy is connected to a Vector2 value which overrides duplicate channel values lower on the node.

w is connected to a Float value.

xyz returns a Vector3 value made from the input components, assigning 0.0 to any channel not defined by the inputs.
xy returns a Vector2 value made from the input components, assigning 0.0 to any channel not defined by the inputs.
zw returns a Vector2 value made from the input components, assigning 0.0 to any channel not defined by the inputs.
x returns a Float value for the x component supplied by the inputs or 0.0 if the channel was not defined by the inputs.
y returns a Float value for the y component supplied by the inputs or 0.0 if the channel was not defined by the inputs.
z returns a Float value for the z component supplied by the inputs or 0.0 if the channel was not defined by the inputs.
w returns a Float value for the w component supplied by the inputs or 0.0 if the channel was not defined by the inputs.

These nodes are used to create transformation matrices to transform geometry in a variety of ways. Depending on the node, the inputs expect either Float or Vector3 types but the output for all of these nodes is type Matrix.

Align

This node generates a rotation matrix to rotate from a source Vector3 to a target Vector3. This node only supports the Vector3 type as input and generates only the Matrix type as an output.

Properties

Matrix Compose

This takes two Matrix inputs and composes them into a new Matrix containing both transformations. As expected, the Matrix connected to the matrix0 input is the first transformation and the Matrix connected to matrix1 is the second transformation. If needing to combine more than two transformation matrices, it is possible to chain Matrix Compose nodes by connecting the previous Matrix Compose output to the matrix0 input and a new Matrix to the matrix1 input.

Inputs

matrix0 is connected to a node providing the first transformation Matrix of the composition.
matrix1 is connected to a node providing the second transformation Matrix of the composition.

Instances

These nodes are used to create instances of input geometry in one of several different methods. In all cases, multiple instances of a specific, non-null geometry are created but the differences come in where they are instantiated and how many instances are created. Several of these nodes use a separate piece of geometry to drive position and location for instances, but this can also be done by setting positions and count manually. Each node in this set, however, outputs only the instanced geometry and not the source geometry used to generate positions and/or number of instances. Additionally, these nodes generate a single geometry rather than individual instances, so there is no need to merge them after these nodes.

Instantiate

This node generates instances of non-null geometry wired to an input based on the count input. If a null geometry is passed to the node during an iteration, the node will continue to iterate until the required number of non-null instances are created. These instances will be output as a single geometry rather than multiple instanced meshes. The transform of each instance is taken from the matrix input which will override the inputs below it OR is taken from the inputs for position, rotation, and scaling. Like the Vector Converter node, if the matrix input is connected then position, rotation, and scaling are ignored as the matrix input will account for the entire transformation of the instance.

Properties

count is an input field for an Int value to be used to determine the number of instances to create. This property is only visible if there is no wire connected to the count input.
translation is an input field for a Vector3 value to be used to translate the position of each instance. This property is only visible if there is no wire connected to the translation input.
rotation is an input field for a Vector3 value in radians to be used to set the rotation of each instance. This property is only visible if there is no wire connected to the rotation input.
scaling is an input field for a Vector3 value to be used to set the scale of each instance. This property is only visible if there is no wire connected to the scaling input.

Advanced

Evaluate context is used for optimization in the graph when using successive iterable nodes. If this property is set to true, each iteration in this node will also calculate all looped context feeding this node. If there are several iterable nodes connected in sequence, the calculations become exponential with every iteration of the current node calculating every iteration of the previous node back to the beginning of the chain. This can cause a spike in process time in the graph. Disabling evaluate context will prevent nodes from initiating evaluations of previous context each iteration which will greatly speed up the graph. However, since there may be a case where it is desireable to re-evaluate context with each iteration of a node, this parameter is available to the user and defaults to true. If a graph seems to be taking too long to process, check iterable nodes to see if disabling the evaluation of context will help improve performance.

position is connected to a node providing a Vector3 to set the position for each instance.
rotation is connected to a node providing a Vector3 using radians to set the rotation for each instance.
scaling is connected to a node providing a Vector3 to set the scaling for each instance.

Outputs

output is the geometry generated from the node. No matter how many instances were created with this node, the output will be a single geometry that has been automatically merged.

InstantiateOnFaces

This node generates instances of non-null geometry wired to the instance input on this node. If a null geometry is passed to the node during an iteration, the node will continue to iterate until the required number of non-null instances are created. These instances will be output as a single geometry rather than multiple instanced meshes. The instance positions are driven by a source geometry connected to the geometry input. Each instance will be distributed across the available faces of the source mesh. The position of each mesh will be a randomly generated position coplanar with and within the bounds of the target face. If there are fewer instances than faces on the source geometry, not every face will be assigned an instance. However, if there are more instances than faces in the source mesh, each face in the source mesh will be assigned one or more instances. If there is a connection made to the matrix input of this node, the transformation of each instance will be driven from this input. Any connections made to the matrix input will override any connections made to the inputs below it. If nothing is connected to the matrix input, the transformation is taken from any connections to inputs for position, rotation, and scaling.

Properties

count is an input field for an Int value to be used to determine the number of instances to create. This property is only visible if there is no wire connected to the count input.
rotation is an input field for a Vector3 value in radians to be used to set the rotation of each instance. This property is only visible if there is no wire connected to the rotation input.
scaling is an input field for a Vector3 value to be used to set the scale of each instance. This property is only visible if there is no wire connected to the scaling input.

InstantiateOnVertices

This node generates instances of non-null geometry wired to the instance input on this node. If a null geometry is passed to the node during an iteration, the node will continue to iterate until the required number of non-null instances are created. These instances will be output as a single geometry rather than multiple instanced meshes. The instance positions are driven by a source geometry connected to the geometry input. The number of instances created will be determined by the vertex count of the source geometry and the density input value using a 0.0 - 1.0 range. Density defines the percentage of randomly selected vertices that will have an instance created at its position and each will receive exactly one instance. If there is a connection made to the matrix input of this node, the transformation of each instance will be driven from this input. Any connections made to the matrix input will override any connections made to the inputs below it. If nothing is connected to the matrix input, the transformation is taken from any connections to inputs for position, rotation, and scaling.

Properties

density is an input field for a float value with a range of 0.0 - 1.0 which determines the percentage of randomly selected vertices that are eligible to for an instance. This property is only visible if there is no wire connected to the count input.
rotation is an input field for a Vector3 value in radians to be used to set the rotation of each instance. This property is only visible if there is no wire connected to the rotation input.
scaling is an input field for a Vector3 value to be used to set the scale of each instance. This property is only visible if there is no wire connected to the scaling input.

Advanced

Evaluate context is used for optimization in the graph when using successive iterable nodes. If this property is set to true, each iteration in this node will also calculate all looped context feeding this node. If there are several iterable nodes connected in sequence, the calculations become exponential with every iteration of the current node calculating every iteration of the previous node back to the beginning of the chain. This can cause a spike in process time in the graph. Disabling evaluate context will prevent nodes from initiating evaluations of previous context each iteration which will greatly speed up the graph. However, since there may be a case where it is desireable to re-evaluate context with each iteration of a node, this parameter is available to the user and defaults to true. If a graph seems to be taking too long to process, check iterable nodes to see if disabling the evaluation of context will help improve performance.
Remove duplicate positions is used to prevent instances from being assigned to vertices that share the same position with another vertex in the source geometry.

Inputs

geometry is connected to a node providing a source geometry to distribute instances upon.
instance is connected to a node providing a geometry from which to create instances.
density is connected to a node providing an Float value in a range of 0.0 - 1.0 which determines the percentage of randomly selected vertices that are eligible for an instance.
matrix is connected to a node providing a transformation matrix to set position, rotation, and scaling for each instance.
rotation is connected to a node providing a Vector3 using radians to set the rotation for each instance.
scaling is connected to a node providing a Vector3 to set the scaling for each instance.

Outputs

output is the geometry generated from the node. No matter how many instances were created with this node, the output will be a single geometry that has been automatically merged.

InstantiateOnVolume

This node generates instances of non-null geometry wired to the instance input on this node. If a null geometry is passed to the node during an iteration, the node will continue to iterate until the required number of non-null instances are created. These instances will be output as a single geometry rather than multiple instanced meshes. The instance positions are driven by a source geometry connected to the geometry input. All instances created will be positioned randomly within the source mesh volume. The number of instances created will be determined by the value connected to the count input on the node. If there is a connection made to the matrix input of this node, the transformation of each instance will be driven from this input. Any connections made to the matrix input will override any connections made to the inputs below it. If nothing is connected to the matrix input, the transformation is taken from any connections to inputs for position, rotation, and scaling.

Note that this node needs to make several ray casts to ensure all instances fall within the volume of the source mesh so this node can be quite slow. Keeping the source mesh simple and the number of instances few will help optimize the time this node requires, but expect this node to be resource intensive whenever it is used.

Properties

count is an input field for an Int value to be used to determine the number of instances to create. This property is only visible if there is no wire connected to the count input.
rotation is an input field for a Vector3 value in radians to be used to set the rotation of each instance. This property is only visible if there is no wire connected to the rotation input.
scaling is an input field for a Vector3 value to be used to set the scale of each instance. This property is only visible if there is no wire connected to the scaling input.

Misc

These nodes are largely to help with organization and debugging a graph, but there is also some utility to be found in them. Node graphs are notorious for being difficult to read once they get complex due to the spaghetti of wires that often occurs within large graphs. That's where both the teleport nodes and the elbow node come in. These nodes help reduce some of the wire complexity in graphs, making them much easier to read. Debugging the graph can also be challenging especially when large arrays of values are being pushed through the graph. The debug node is crucial for being able to see values passed along any wire at any point. Lastly, the GeometryInfo node can be used as easily to debug the graph as it can to drive logic within.

Debug

The debug node is a very simple node that can be connected to Float, Int, Vector2, Vector3, Vector4, and Matrix types. While the node can be manually connected between two nodes, simply dropping a debug from the graph on an existing wire of a supported type will automatically connect the node in the middle of the existing wire. Alternatively a debug node can be inserted into an existing wire simply by holding crtl and left clicking any compatible wire. And while these methods of quickly inserting a debug node require it to be inserted between two nodes, the debug node does not require a connection to its output to function. It can be a terminal node in the graph if needed to debug a value that isn't easily connected back to the graph flow.

The node doesn't do any calculations in the graph, only displays the values carried along the wire in the properties panel. Simply select the node and the panel will display whatever value is being passed. This also works for iterable nodes that may contain an array of values. Since the debug node is only used to display information in the UI, there is no cost to the node and debug nodes can be left within a graph much like an elbow node if desired.

Note: There will be times when the display of debug values will be truncated due to the length of the values not fitting within the width of the UI panel. If this happens, simply hover the cursor over any displayed value and a tooltip will appear showing the value in its entirety.

Inputs

input can be connected to a node providing a Float, Int, Vector2, Vector3, Vector4, or Matrix type.

Outputs

output is a passthrough of the value connected to input of the same type. Note that the debug node only works if it is connected to a path that reaches the GeometryOutput node. If the output does not connect to GeometryOutput at some point, this node won't be evaluated and will not show any debug values when selected.

Elbow

The elbow node is an organizational node to help route wires within a graph. It is a passthrough node that supports Float, Int, Vector2, Vector3, Vector4, Matrix, and Geometry types. The use for this node is just to re-route wires to help with graph organization and it adds no time to the graph calculations so many can be used with no sacrifice to performance. Elbow nodes can be used sequentially as well to perform multiple bends in a wire to detour around congested areas of the graph. Like any other node, an elbow also supports multiple connections to its output port so it can be used to split one wire into many when needed.

Inputs

input can be connected to a node providing a Float, Int, Vector2, Vector3, Vector4, Matrix, or Geometry type.

Outputs

output is a passthrough of the value connected to input of the same type.

GeometryInfo

This node is also a passthrough node for the Geometry type which adds no time to a graph. It does perform one important task which is supplying access to information about the associated geometry at this specific point of the graph. There may be need to access information like vertex count for debugging purposes which can be fed directly to a debug node. Alternatively, the collectionID of the geometry might be needed to help drive logic in the graph through nodes like equal. This node is flexible enough to fit many different needs which is why it has been added to this group.

Inputs

input can be connected to a node providing a Geometry type.

Outputs

output is a passthrough of the Geometry type connected to input.
id is an Int representing the ID of the current Geometry.
collectionID is an Int representing the ID assigned to this Geometry by a collection to which it is assigned.
verticesCount is an Int representing the total number of vertices in this Geometry.
facesCount is an Int representing the total number of faces in this Geometry.

TeleportIn

This node is an organizational node to help reduce the complexity of overlapping wires within a graph. It is a passthrough node that supports all data types. This node works in conjunction with the TeleportOut node to make a connection, often far across a graph, without the need for a wire. This node can be connected to any node to create a reference to the value passed by the connected node. When connecting the TeleportIn node to another node, it is important to rename this node to a unique name as this name will be referenced by the TeleportOut node. On the TeleportOut node, selecting the name used by this node as the entry point will create a reference to the value connected to the TeleportIn node. In this way, a single value can be used in several places of a graph without the need to stretch wires across the graph.

Inputs

input can be connected to a node providing a Float, Int, Vector2, Vector3, Vector4, Matrix, or Geometry type.

TeleportOut

This node is an organizational node to help reduce the complexity of overlapping wires within a graph. It is a passthrough node that supports Float, Int, Vector2, Vector3, Vector4, Matrix, and Geometry types. This node works in conjunction with the TeleportIn node to make a connection, often far across a graph, without the need for a wire. Setting the entry point property on this node will tell the node which value to reference. Each TeleportIn node in the graph will be available to the TeleportOut node and it can be changed just by selecting a new entry point if needed. In this way, a single value can be used in several places of a graph without the need to stretch wires across the graph.

Properties

Entry point is the specific TeleportIn node that is referenced by this node.

Outputs

output is the value referenced by the selected entry point in a type that matches the referenced value.

Updates

These nodes will update connected geometry in one of several ways. It could be assigning it to a collection, merging with other geometry, or setting one of the various properties of geometry like colors, material IDs, normals, positions, tangents, or UVs. These nodes, like the math nodes, are some of the most commonly used nodes as they perform very important operations for creating geometry.

Collection

This node creates a collection of up to 10 geometry inputs. When used in conjunction with one of the instantiate nodes, the collection will provide one random geometry from the collection per iteration of the instantiate node. This allows for more randomization when creating a procedural mesh. The collection also provides a unique collection ID to each included geometry to help drive logic within the graph. The collection ID can be accessed with the GeometryInfo node.

ComputeNormals

There are times when it is necessary to recompute normals when creating geometry. This node is simply there to handle any computations of normals that are needed.

Inputs

geometry is connected to a node providing a Geometry type.

Outputs

output is the geometry after computing normals.

Mapping

When working with geometry, it is often necessary to create a new UV mapping for it such as when the geometry has been optimized or if an additional UV set is desired. This node will create new set of UV coordinates for the geometry based on the projection method selected. The available projections are spherical, cylindrical, and cubic and more may be added in the future. Simply pass the positions contextual value to the position input and a Vector3 to the center input to define the center of the projection and create UV coordinates for each vertex.

Advanced

Mapping defines the projection method for mapping UV coordinates from the available options of spherical, cylindrical, and cubic.

Inputs

positions is connected to the positions contextual value node to provide the vertex list to the node.
center is connected to a node a Vector3 position for the center of the projection.

Outputs

uv is the geometry after computing normals.

Merge

A common operation when creating procedural geometry is to merge two or more different meshes. This node will merge up to five geometry inputs into one using a simple merge. This node does not do any type of boolean operation and does not change the vertex lists or UV coordinates at all. If multiple meshes are merged which have different material IDs, a MultiMaterial will be created and assigned to keep the original material breaks of each geometry. When using the Merge node, please note that the advanced property Evaluate Context is disabled by default for performance reasons. If the prior context is not evaluated then any procedural generation of values done before the merge node will be executed only once. If the output of that merge node is then used in any instantiate loop, all instances will be exactly the same. If it is desired that merged geometry built procedurally be unique with each instance, the Evaluate Context property on the Merge node must be enabled. Remember that enabling Evaluate Context on a merge node will increase the time needed to generate the final geometry, so it is important to be prudent on how many nodes must be evaluated before merging, especially if the output of the merge is then used as the source for instancing.

Advanced

Evaluate context is used for optimization in the graph when using successive iterable nodes. If this property is set to true, each iteration in this node will also calculate all looped context feeding this node.

geometry3 can optionally be connected to a node providing a Geometry type.
geometry4 can optionally be connected to a node providing a Geometry type.

Outputs

output is the merged geometry made from those available through connected inputs.

Optimize

There are times when a geometry will have unwelded vertices where multiple vertices occupy the same position. This is common when using glTF files as the specification states that vertices that lie on a UV seam should be split for optimization reasons. If working with geometry that has unwelded vertices that need to be merged, use the optimize node. This node does a simple operation that merges any vertices that share the same position within a certain epsilon. This operation is destructive in that it creates a new triangle list and deletes all vertex parameters other than positions. This means that any mesh that has been optimized will need new normals, tangents, and vertex colors. Typically, the first node connected after an Optimize node would be a ComputeNormals node.

Noises

These nodes are used to create randomize values used for various operations in procedural geometry creation.

Noise

This node provides a simple 3D Perlin noise to generate a volume of randomized values between 0.0 and 1.0. The properties of the noise can be set to create a range of different value patterns.

Properties

offset is an input field for a Vector3 value to be used offset the noise texture. This property is only visible if there is no wire connected to the count input.
scale is an input field for a Float value to be used to scale the noise texture. This property is only visible if there is no wire connected to the rotation input.
octaves is an input field for a Float value to be used to adjust the number of octaves to the noise texture which increases the frequency of the pattern resulting in increased detail in the texture. This property is only visible if there is no wire connected to the scaling input.
roughness is an input field for a Float value to be used to adjust the amplitude of the octaves in the noise texture which adds contrast to the texture. This property is only visible if there is no wire connected to the scaling input.

Outputs

output is the noise texture as a Float type.

Random

This node provides a random value between a minimum value and a maximum value. This node can support Float, Int, Vector2, Vector3, and Vector4 types. The type for the node connected to the input of this node determines the type for the node output. When using this node with iterable nodes, the node will return a new random value per iteration. Iterable nodes include SetColors, SetNormals, SetPositions, SetTangents, and SetUVs as the operations are performed for every vertex in the geometry. If a random node is used before one of these iterable nodes, a new random value will be generated for each iteration. This is also true for all of the instantiate nodes where the node will loop a certain number of times based on inputs. For more control, the Random node also has an advanced property to lock the value per loop so that the random value will be the same for each iteration or loop. Note that this property only applies to the nearest iteration or loop being performed by a node. This means if a Random node feeds a SetColor node which in turn feeds an Instantiate node, locking the value per loop will apply only to the SetColor node and not the Instantiate node.

Advanced

Lock per loop will return one value per loop rather than a different random value for each loop when enabled.

Inputs

min is connected to a node providing a value to be used as the minimum bounds for the random range.
max is connected to a node providing a value to be used as the maximum bounds for the random range.

Outputs

output is the random value as a Float type.

Output Nodes

These are required nodes for the graph to create an output geometry.

Geometry Output

This node is required to create the geometry and whatever is connected to this node is the final geometry for the graph. This node does not have any special considerations for use, but there are some useful things to know about it. Selecting the node will display useful information about the geometry output that is rendered which include vertices, faces, build time, and sub-meshes. The node also gives stats about if the geometry has normals, vertex colors, UVs and the number of sets, tangents, matrix weights, and matrix indices.
