The issue i'd like to solve is how to project 2d texture files (tiffs for example) onto geometry just like the projection node of maya does.
I would like to use a native Mental Ray node because, first of all, as far as I know keeps the workflow fast and light. (Is that true anyway?)
The second reason is that I cannot manage to render a bump in a mental ray shader starting from maya's projection node. How should I connect it to the shader? I'm currently using a mia_material.
