mia material x passes - problem
 

Have a look at these two renders. One is a basic lanbert and as you see, the rendered mesh is fine.

However, take a look at the render with the mia_material_x_passes...there are parts of my mesh that are not rendering as expected. I have assigned the material to all of the mesh.

Any ideas guys as to where I can look to resolve this issue?

Sorry for the double post

The first image is missing....

Are the normals facing the wrong way ?? - its the only thing I can think off looking at the render as the shadder is working in other places - its even reflecting the bad area`s (hehe). It some times happens when duplicating over groups and i think may have happened here.

I wen tin and unparented my mesh items and discovered where the normals were wrong.

Cheers :)
