Generate Weightmap
This node generates a weightmaps from input sources.
Generate Weightmap
Method #
This node generates per-vertex weight values which can be used by other nodes - particularly other deformers - as part of their processing.
Deformers such as the 3D Plasma Deformer have an input called “Generated Weightmap” which takes a Generate Weightmap Deformer as input; the per-vertex weight is then used to scale the deformation.
This node outputs a vertex weightmap for the mesh that can be used to control where on a surface a Deformer is allowed to modify the parent mesh.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Blend Amount Global override for how much the deformer affects the mesh.
Subdivision Order Toggle whether the deformer is added before or after the object is subdivided.
- Before Subdivision : The deformation is applied before any subdivision is added.
- After Subdivision : The deformation is applied after subdivision, or inbetween if the subdivision level property is modified.
Subdivision Level The subdivision level at which the deformer is applied. Subdivision Order must be set to After Subdivision to Function.
Weightmap Add a weight map to determine where the deformer is more or less effective.
Vertex Source Mode Choose whether the deformer applies to the individual vertices or the mesh chunks.
- Vertex Positions : The mesh deformations are applied to the mesh vertices.
- Chunks : The mesh deformations are applied to the separated mesh pieces.
Deformer Transform Space Choose which transform space the deformer uses for deformation. Does not affect falloffs.
- Local : Deformations are calculated in the Local Space of the object, so transformations of the parent mesh will not affect the deformation.
- World : Deformations are calculated in the World Space of the scene, so transformations of the parent mesh will apply the deformer differently depending on the mesh position.
Update Time Mode How the deformer updates with relation to the timecode.
- Locked To Timecode : The deformer deformations are locked to the timecode and the same time will always yield the same deformations.
- Running / Looping : The deformer deformations are disconnected from the timecode and will loop seamlessly at the end of the layer.
Mode The mode by which the value is generated.
- Falloff Only : The deformer’s falloff parameters are used to calculate the weight.
- Texture Coordinate - X : The X component of the geometry’s texture coordinate is scaled by the falloff and used as the weight.
- Texture Coordinate - Y : The Y component of the geometry’s texture coordinate is scaled by the falloff and used as the weight.
- Texture : An input texture is sampled using the geometry’s texture coordinates and the luminance of the sampled pixel is used as the weight.
Gain Scale the weighting per vertex for all vertices.
Offset Offset the generated weights for all vertices.
Min Value Limit the minimum weight generated for all vertices.
Max Value Limit the maximum weight generated for all vertices.
Invert Invert the weights across the weightmap.

UV Offset Y Offset the UV texture along the Y axis. Only functions with one fo the texture modes selected.
Texture Wrap Mode U Controls how textures used by Weightmap are wrapped when the U value range exceeds 0 to 1. Only functions with one fo the texture modes selected.
Texture Wrap Mode V Controls how textures used by Weightmap are wrapped when the V value range exceeds 0 to 1. Only functions with one fo the texture modes selected.
Show Weightmap Visualise the weightmap as vertex colours on the source geometry.
These properties control where the deformer affects the geometry.
Parameter Details Falloff Enabled Enable falloff from the position of the deformer.
Falloff Shape Select which shape to use to draw falloff from.
- Sphere : How quickly the falloff drops to 0 at the outer falloff.
- Cylinder - X : Falloff is drawn radially outward from a line along the x axis, forming a cylindrical falloff.
- Cylinder - Y : Falloff is drawn radially outward from a line along the y axis, forming a cylindrical falloff.
- Cylinder - Z : Falloff is drawn radially outward from a line along the z axis, forming a cylindrical falloff.
- Plane - X : Falloff is drawn outward from a plane formed on the YZ axis.
- Plane - Y : Falloff is drawn outward from a plane formed on the XZ axis.
- Plane - Z : Falloff is drawn outward from a plane formed on the XY axis.
Falloff Range Limits the range the deformer is effective at.
Falloff Inner Range The inner range from which the falloff is calculated from.
Falloff Curve Power How quickly the falloff drops to 0 at the outer falloff.
Invert Falloff Invert the direction of the falloff.
Falloff Curve Visualises the falloff curve, from being completely in effect to no longer effective.
