Null To Weightmap

This node converts a position to a weightmap.

Example .dfx

Method #

This deformer node uses the distances from a set of input Nulls, or a transform array, to generate 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 weightmap deformers as input; the per-vertex weight is then used to scale the deformation.

Parameters

Attributes

Parameter	Details
Subdivision Order	Toggle whether the deformer is added before or after the object is subdivided.
Subdivision Level	The subdivision level at which the deformer is applied. Subdivision Order must be set to After Subdivision to Function.
Vertex Source Mode	How vertexes are selected to be used by the deformer. Vertex Positions : Vertexes are chosen based on their positions in the scene. Chunks : Vertexes are chosen based on the enclosed section of the mesh they are used.
Per-Polygon Weightmap	Determines whether the weightmap should specify a value per-polygon or per-vertex.
Max Radius	The falloff radius from each null.
Gain	Scale the generated value.
Offset	Offset the generated value.
Sharpness	Ramps the sharpness of the generated value to a power.
Min Value	Limit the minimum value generated.
Max Value	Limit the maximum value generated.
Invert	Invert the generated weightmap values.
Show Weightmap	Visualise the weightmap as vertex colours on the source geometry.

Inputs
