When you see 'GAPP' in the error, it usually means it's coming from mental ray.
'small triangle' usually means there is one or more triangles on the mesh that are scaled to zero area/size. Mental ray doesn't like that. I think the minimum allowed is 0.001. If you need to not display triangles, it would be better to hide them or apply a shader to do the same.

We have an ICE structure made up of animating ICE blobs, and are trying to use the Fast SSS shader, but we get a geometry error when we try and render an image. The ICE blob surface renders fine with a simple Phong shader, for example, so there is no problem with the ICE cloud itself, just when we try the Fast SSS shader. Are there any known problems with the Fast SSS shader and blob particles? These are the error messages: // WARNING : GAPP 0.11 warn 092123: displacement: removed small triangle // WARNING : GAPP 0.5 warn 092037: triangulation of polygon list from object _0@5:2460::blbo@00000355 failed Thanks so much ahead of time, Leoung
