I’m using matchmaker brush extensively in my work. With version 4R, the subtool turns black after being “matched”. Clearing mask, or trying to change material doesn’t seem to work. It’s very hard to work these subtools because they don’t seems o have any detail or depth. Please help, this worked so well in the previous version!
I just tested it out and I can’t repeat the problem you are having. Perhaps its an issue for support specific to your system.
OK, this was very basic problem. Seems that matchmaker defaults to RGB, but should be Zsub instead. It works now.
