MOI to Keyshot -- best practises ...

Paq, the shader overides the geometry normals so you will not see normal artifacts, try rendering without it.

Maybe your right Michael about it being keyshot. I use Maya and had some normal artifacts which I manually fixed but that was some months ago...I will post updates next time i see it.

I am not sure, but would using FBX fix the issue?
