Never tried cloth mask so this is new for me
Looks like facesets, each face set has a different colour, they are like masks that use face information.
You can turn faceset visibility on and off here:
yes but i made the pruple ones in the middle. the green one was there from before i did it.
Any way to remove the face set?
I don’t think you can delete it on its own (you can clear all-or turn them all into one).
You can use the draw brush to draw over different facesets and “merge” them.
I do not do much sculpting with face sets so maybe there is a way I do not know of.
