Combine Weightmaps

Combine Weightmaps

Updated: 10 Feb 2025

Blends weight maps together
Example .dfx

Method #

This node blends two weightmaps, linked via the “Generated Weightmap” input, to create a new weight map for 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 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.
Blend Amount The blend between the input weightmaps, when mode “blend” is used.
Mode The combine mode.
  • Max : The max of the two weightmap values
  • Min : The min of the two weightmap values
  • Add : Adds the two weightmap values
  • Multiply : Multiplies the two weightmap values
  • Subtract : Subtracts the two weightmap values
  • Blend : Blends the two weightmap values
Gain Multiplies the resultant value.
Offset Offsets the resultant value.
Min Value Clamps the resultant value to a given minimum.
Max Value Clamps the resultant value to a given maximum.
Invert Inverts the resultant value.
Show Weightmap Visualises the weightmap on the vertex colours of the parent mesh.
