Inside this scene is a flat square shape... floating in front of the camera. I need to be able to see through it yet retain the outline of it as a contour.
I've got 2 shaders. Both are colored all black. Their contours are white. One I need to be transparent but still retain it's outline.
Rendering with Mental Ray Contour rendering...
How should I do this? I've tried making the material transparent but that doesn't work.
Does this make sense?
