Prune insignificant smooth skin weights
 
 
 

As you paint smooth skin weights, you might unintentionally create small weight values, for instance, 0.008, on many of the skin points. Maya creates small values as it normalizes total skin weight for each point to 1. The weights have no discernible effect on the skin, but they slow down processing. You can prune the small skin weights to speed up processing.

To prune small skin weights

  1. Select the skin or specific skin points.
  2. Select Skin > Edit Smooth Skin > Prune Small Weights > .
  3. In the Prune Below box, set the threshold weight.
