substituteGeometry([disableNonSkinDeformers=boolean], [newGeometryToLayer=boolean], [oldGeometryToLayer=boolean], [reWeightDistTolerance=float], [retainOldGeometry=boolean])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

substituteGeometry is undoable, NOT queryable, and NOT editable.

This command can be used to replace the geometry which is already connected to deformers with a new geometry. The weights on the old geometry will be retargeted to the new geometry.

Return value

stringName of shapes that were replaced


deformers, replace, geometry, skin


disableNonSkinDeformers, newGeometryToLayer, oldGeometryToLayer, reWeightDistTolerance, retainOldGeometry
Long name (short name) Argument types Properties
retainOldGeometry(rog) boolean create
A copy of the old geometry should be retained
oldGeometryToLayer(ogl) boolean create
Create a new layer and move the old geometry to this layer
newGeometryToLayer(ngl) boolean create
Create a new layer for the new geometry.
disableNonSkinDeformers(dnd) boolean create
This flag controls the state of deformers other than skin deformers after the substitution has taken place. If the flag is true then non-skin deformer nodes are left in a disabled state at the completion of the command. Default value is false.
reWeightDistTolerance(wdt) float create
Specify the distance tolerance value to be used for retargeting weights. While transferring weights the command tries to find the corresponding vertices by overlapping the geometries with all deformers disabled. Sometimes this results in selection of unrelated vertices. (Example when a hole in the old geometry has been filled with new vertices in the new geometry.) This distance tolerance value is used to detect this kind of faults and either ignore these cases or to vary algorithm to find more corresponding vertices.
