Occlusion Weightmap
Updated: 10 Feb 2025
Generates a weightmap from concave areas in the mesh
Occlusion Weightmap
Method #
This node genreates per-vertex or per-polygon weightmap based on the concave areas 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.
Parameters
These properties control the core behaviours of the node.
Parameter Details Apply Mode Choose whether the deformer applies to the individual vertices or the mesh chunks.
- Vertices : The mesh deformations are applied to the mesh vertices.
- Chunks : The mesh deformations are applied to the separated mesh pieces.

These properties control where the deformer affects the geometry.
Parameter Details Use Falloff 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.
