Hey steventaylor, thanks for your reply. I was hoping to get your feedback on a problem I encounter when painting in Zbrush. Here is an example the problem. This is a piece I am working on, and I blocked in all the colors and main forms just fine, but when I lower my opacity to start refining and blending and get more color gradations I get weird results. In the second pic below I picked a very dark grey almost black color but when I paint it on I get reds and yellows, it seems that when colors overlap they get lighter instead of darker
This has been a frustrating problem for me as I do a lot of very low opacity painting. Have you experienced this
Any advice or feedback would be appreciated.
