I've been trying to find information on why placing modeled rocks in a water shader causes the rocks to render black (or near black.) At first I thought it would be a simple transparency adjustment, but I haven't been able to figure it out yet. Searching the forum for "water shader" hasn't given me the answer yet, or maybe I'm too dense to see it.
So if someone could point me to a thread, tutorial, or a brief "do this", I'd appreciate it.
