I want to render something in which part of the image is done with and edge, and part of it is not. The models are overlapping, so if I render them separately and the re-combine, one is on top of the other.
There must be a compositing technique for doing this, but cannot figure out.
Can someone please give me some advice? Much appreciated.
Attached are simplified examples of what I am talking about. I would like the balls outlined but the lines not to be.
