Red paint. Same shader. I added more control parameters. There are gravity effects, where droplets hang down from surfaces. Unfortunately, this makes the bottom of the upper eyelid extend downward.

I think the use of a control mask is going to be needed for this shader. Like a transmap, it will control where the affect is applied.

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)
