I’m unable to get any of the smooth tools to respect Mask by Polygroup. Not sure if this is a bug or I’m doing something wrong.
did you turn the option on while you had a smooth brush active? Basically, while holding shift?
ya, it seems to be that it works for high subdivs but not when I’m smoothing my base level
That slider is not tied into Brushes (Shift Ctrl etc). It is a global setting for all brushes. Topological Button is tied in the the brush hot keys though - just FYI.
You might try the Topological Button instead and see how that works. Keep in mind that you will see some soothing on adjacent polys. Inevitable.
Topological does not seem to work for masking but it works for some other brushes.
