Hi All-

I am trying to do a render using Mental Ray. My character is a sub-d object. When I hit render, I get an error message:

Error: (Mayatomr.Geometry) : polyToSubdShape1, non-quadrilateral face in subdivision surface base mesh //

What does this mean and how can I fix the problem?

i think its saying theres a ngon somewhere so you need to find it and split it into quads or tris
im thinking thats the prob but i could be wrong

...only QUADS if you want to render Sub-Dīs with MR!

this is what it says in the manual about it.

" Subdivision surface rendering is now supported.
The support for subdivision surfaces has been added and includes hierarchical edits, hierarchical material assignments, edge and vertex full creases only, uncreases, texture reference objects, deformation motion blur, and derivatives ( for bump mapping and texture filtering ) . Unlike Maya, however, mental ray for Maya can handle only quadrilateral base meshes ( a number of Maya standard subdiv shaped are therefore rejected)... "

so yah basicaly what they said ;) hope this helps.. also on a side note I ran into the same problem so I just started using poly smooth and I like the results for the most part better, not to mention the poly smooth proxy seems to work faster then sub D poly prox.. for me anyhow.
