I've build and textured a model of a human face which I'm more or less happy with. I wanted to paint s second texture for my render system which uses some sort of parallax texturing. On that second texture I want to paint veins that cover the face. In the end these veins and the rest of the texture shine dynamically blended through the first one.
But this gives me a hard time. Any ideas or experience on how to paint veins that doesn't look like some colored cables? And it can be a bit emphasized since this will be partially occluded by the first texture.
