I am attempting to render "smooth" meshes for a scene in Maya. Renders fine in Maya Software mode (but doesn't show smooth meshes) but when I switch to Mental Ray the render comes out black. All materials are Lambert, all textures are jpegs.
I'm using Maya 2012, supposedly smooth mesh is supposed to be renderable but only in mental ray. I've also tried rendering in Mental Ray with smooth turned off and it still comes out black.
You're better off sticking with the standard Mental Ray Materials anyways. Mia_X_Material_Passes should be your go to solution for just about everything that's not car paint or skin. Feel free to keep using those Maya Utility nodes though.
