hi,

I'm rendering a scene in MR with final gather, I use a simple sss shader and two directional lights. The hoop displayed below is apoly object I extruded using two circles. The main circle has a twist deformer applied to it so my hoop deforms.
Now on a couple of frames I get these wired rendering glitches like in the image. I get an error message in the command line

"// Warning: (Mayatomr.Scene) : hoopShape: shapes are not equivalent, no motion vectors computed // "

I'm a bit helpless with this one and I got to deliver the project tomorrow, so the situation is real bad,
Any help greatly appreciated
