Another demonstration, using that modified texture. I added the bump maps and did a few standard tricks for shaders and lighting. I exaggerated the bump, just to make it easier to see how clean and detailed the bump texture features can be with the better render settings. Otherwise for real work I'd use less.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
