I have a scene with some nurbs objects, and when I goto render the scene everything works as expected.

However when I run a batch render for an animation, some of the surfaces render very strangely.

In this pic, the back of the legs should be one solid white colour, but in batch mode it comes out oddly fragmented.

(This is in Maya 8, from a scene that was originally done in Maya 6. In 6 I didn't have this problem)

ANyone runn into anything similar?
