[RenderMan render]

I have a problem with Renderman.

1. I import a model into "Paint UV Mapped mesh (per-Pixel)" room.
2. I paint the model with a smart material.
3. I go to Render room and choose Renderman as a render engine .
4. I click Render Preview or FinalRender. The renderer begins to render and when it reaches the painted model 3D-Coat crashes - every time.

Could someone explain me why 3D-Coat crashes?

(When I do the same, but import the same model into "Vertex Painting", everythong is okey, i.e. Renderman renders without a problem).

 

[3D-Coat 3.0 ALPHA]

V35 crashes when I click volumetric sculpting icon. I have sent the bug report.
