MR ignoring material ?

CreativeSheep

I did some searching online for why I'm getting the; no material assigned, ignored error.  Mental Ray for Maya simply ignores as the error states, the object.  I've applied the same material numerous times but the object doesn't render ?

Does the material have a shading group node? Does it work on other meshes in this scene?

The material does have a shading group node.  The same material did work on another test object; I assume it has to do with the one object, what is the problem ?

I can't think of any definitive thing other than "Well, Maya works funny sometimes". There are some cases where lambert1 is assigned to a mesh even when it shouldn't be, check the hypergraph w/hierarchy with your mesh selected and delete the connections to it if that's the case. Or even delete all the shader connections and reassign them again. Failing that, I'd suggest the usual mesh>cleanup, combine with a cube, export and reimport obj and see if that helps.

Exporting then re-importing solved the problem.  Next time I'll know, thanks for the time to help
