Attribute Weightmap
Updated: 10 Feb 2025
Generates a weightmap from attributes of the parent geometryUpdated: 10 Feb 2025
Generates a weightmap from attributes of the parent geometryThis node generates per-vertex or per-polygon weight values using attributes and structure of the parent mesh. These can then be used to vary the strength of Deformers on the parent mesh.
The output from this node is a vertex weightmap which is unique to the parent mesh, so can’t be used to influence other meshes.
Node placement is important! Weightmaps are generated following the deformer processing stack, so make sure to place the weightmap at some point before the deformer its applied to.
These properties control the core behaviours of the node.
Parameter | Details |
---|---|
Weightmap | Add a weight map to determine where the deformer is more or less effective. |
Mode |
The mode by which the value is generated.
|
Per-Polygon Weightmap | Should the weightmap generate a single value per polygon, or interpolate the value over the surface. |
Gain | Scale the generated value. |
Offset | Offset the generated value. |
Sharpness | Applies a power to sharpen the generated value. |
Min Value | Limit the minimum value generated. |
Max Value | Limit the maximum value generated. |
Invert | Invert the generated weightmap values. |
Material Index | The material index to compare to. |
Smooth Group | The smoothing group to compare to. |
Show Weightmap | Visualise the weightmap as vertex colours on the source geometry |
