How do I paint over something in the same layer in a symbol?
I am trying to make a symbol of a rock that has a specific shape of shading. I want the original shape underneath to stay but when I use the "paint inside" brush on the rock, the shading "replaces" the region of the rock part. I just want the shading to go over the whole rock, not replace it. I tried making two layers, one for the rock and another for the shading, but "paint inside" wouldn't work then. What should I do?
