Indoda your image looks like your lights are altogether too strong. If that is my shader, the skin is being washed out by the lights. Your image looks like mine on the right. It should more like the one on the left.

Both of these were done using the nostril mask technique applied to my complex shader as I wrote in post #23 - no shadows were generated in this image.

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)
