>>I didn't quite understand what you said about Cloud or fractal texture. I have Vistapro, so I think I can generate a cloud mesh.<< Not quite was I was meaning. Some program has a texture generator that makes cloud like fractal plasmas or some such. They look kinda like clouds. Or fog. Or mist. Basicly just random blotchy fuzzy stuff. All 2d. One of these overlaid or merged or modulating your picture might add that uneven tone and shade. You can get something that might do just by painting around in gray scale with a big airbrush tool. Then maybe soften. >>One other thing I didn't understand was when you said that the paintings should respond only to the bump map of the rock. […] The texture for this stones is a rock pattern, with the paintings. The Bump map affects the whole image the same way.<< Ah, you have the rock face and the painting on the same bitmap? OK… I'll try again. Longer. Imagine that there are no paintings on the rock. The whole rock has some rocky texture. Rough and bumpy. You use this as a bump map, and it looks good. Now some ancient Celt comes along and paints on top of the rock. My understanding is that this type of painting would be a thin colouring on top of the rock. The same rough and bumpy rock surface would show through where the painting is. Run your hands over the painting and you will feel rock. If you use a bump map for your rock that looks only like rock, then the painting will look right. If you use a bump map that includes the painting, the painting will look like it is standing out from the rock. You'd be able to feel the painting with your fingers. I think this would be wrong. Simply – use the rock mesh. use a rock like bump map. use a second map that looks rock like and also has your painting. Or there may be some stuff you can do with labels – Anyone? – gruhn (did that help?)
