Hello!
I have encountered an interesting fact. RMfM generates shaders ".slo" and puts them in the directory /scene name/shaders. It calls them the same name as the shaders, however, if I render a seqence on more then one machene sometimes frame that renders first cleans-up the files - result is a corrupt render for the other frame.
Another instance of this problem is animated shaders. Same thing, on the distributed machenes they will call the same shader, rather then something like labmert1.frame_number.slo
