render problems

Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Wow that looks just like maya vector rendering, but you said it was mentalray. Check your render globals mentalray section and scroll down to your renderlayer/pass control to see what is checked. You will have to enable the global passes option by checking it. It looks like color is the only thing checked.

EDIT: I checked my Mr settings to see if I could do the same with my mental ray and I couldn't make it work like that by just checking color. Are you sure you are using mental ray and not the Maya vector renderer instead?

create a new lambert shader and add it to all the objects and render to see if it's a material problem or something else.

If that renders normally create a new material and recreate one of the original mats apply and render to see if it has something to do with exporting to MB and then importing back to maya that is borking the materials

Try exporting your mesh as an .obj and re open in maya.

problem with importing as an obj is that it seems to almost double the poly count from 58k to almost 100k
