A lambert shader, placed on torus with UV, rendered in Maya render looks fine:

An Octane checker on the same geometry in Standalone renders ok (once set to UV):

but the geometry in Octane for maya looks like this:

May be doing something wrong here, but have:
OctaneScaleTransform in the Transform slot
Projection slot is empty (when I put in an OctaneUV, the geometry disappears)
cheers,
