LOL - sorry I didn't answer - was busy watching TV. I'll post the material room settings for the water and sand tomorrow. But the short answer is I used a math node to add them together the cellular and noise together. Sometimes you feed one node to another, sometimes you just add'em up. DrMCClark - I remember seeing your question about the water effect a while back. That post got me thinking about it and led to the picture. But the search engine is such crap I couldn't find your post to tell you about it. But now we've found each other so all is good. PabloS, you crack me up. Cya in the morning.

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)
