I dont know what is wrong with my model here, I have been using this model for quite a while with no problems, and suddenly I have these brown patches in rendering. I tried putting the original geometry file back in and no luck. Does anyone know whats going on here and how I can fix it? Thanks!

This is rendered in P5? If so, apply a texture map, any texture map, to the Displacement node, with a displacement of .000001, and enable Displacement in the Firefly renderer. Two-sided faces do things like this in P5.

The displacement map thing didnt work :-(

I have goten something similar to this by over producing a spotlight. When i say that, I mean, raising and lowering values ALOT between renders as well as moving them. I'm probably way of base though. I couldn't say for sure this is what your experiencing. Questiong: would you say those patches corespond to the figure meshes (robe's) geometry? That is to say, if you switched to a mesh view, would that triangle near the centre BE a triangle in the mesh? Just wondering, it may narrow it down to a mesh-fart (with what and why i dont know) rather than a texture.

heyas; i dunno, but it looks as if somehow you have two identical clothing meshes that aren't exactly overlapping. if it's only in rendering.... um, did you change any polygon smoothing options?
