To automatically smooth the skin weights of your bound character

1. Do one of the following:
   • Select the bound surface for which you want to smooth skin weights.
     
   • Select the specific vertices on your bound surface for which you want to smooth weights.
     
2. Select Skin > Edit Smooth Skin > Smooth Skin Weights > .
   
3. Adjust the Weight Change Percentage value for Smooth Skin Weights. See Weight Change Percentage.
   Note

   You need to set a Weight Change Percentage value greater than 0.0 when smoothing all the vertices on a bound surface.

4. (Optional) Turn on Preview and then click Apply to highlight in the scene view the vertices that will be smoothed by the Smooth Skin Weights operation. The vertices highlight yellow.
   
   Tip

   If many vertices highlight yellow on your character (for example, in the above image), then your Weight Change Percentage value is too low and should be increased.

5. Click Smooth.
