Occlusion Weightmap

Occlusion Weightmap

Updated: 10 Feb 2025

Generates a weightmap from concave areas in the mesh
Example .dfx

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.

ParameterDetails
Apply ModeChoose 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.

ParameterDetails
Use FalloffEnable falloff from the position of the deformer.
Falloff ShapeSelect 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 RangeLimits the range the deformer is effective at.
Falloff Inner RangeThe inner range from which the falloff is calculated from.
Falloff Curve PowerHow quickly the falloff drops to 0 at the outer falloff.
Invert FalloffInvert the direction of the falloff.
Falloff CurveVisualises the falloff curve, from being completely in effect to no longer effective.
