Depending on which Normalization mode you have selected, painting smooth skin weights can create small weight values, for instance, 0.008, on many skin points. For example, with the default Interactive Normalization mode, Maya can create small values as it normalizes total skin weight for each point to 1.
These small weights have no discernible effect on the skin, but they can slow down processing. Pruning these small weights can speed up processing time.
To prune small skin weights
- Select the skin or specific skin points.
- Select
Skin > Prune Small Weights >
to open the
Prune Small Weights options in the
Skin menu.
- In the Prune Below box, set the threshold weight.
