To answer your question, I that it cleared up some alpha or texture�. I tend to work in would think that your could use any size image you designer I know.
Going to convert the file to 16 bit and double the resolution size to see if that makes a difference. When used with painting tools, Alphas determine the shape of the brush being used. The alpha should be a 16 bit grayscale image in. OK thank you for the heads up on what section to post I always had a hard time navigating on this forums.
