compositing geometry "behind" live action footage
by Matthew Macar on May 14, 2012 at 1:08:10 am
Very new c4d user here...I have a quick shot I'd like to create, but am struggling with the technical execution, in terms of rendering. I know how to handle this in Maya, but can't figure it out in c4d, even after a lot of searching.
Basically, I have a plate where subject is shot from behind, standing in front of a wall, as if she's looking at a painting. Locked off shot, though a dolly will occur in post. I've created and animated 'ribbons' that will originate from her chest area, which is between her in the wall, aka, out of view of the camera and the 3d 'camera.' I have gotten the move and everything all laid out, however, I can't figure out how to 'hide' the bits that exist behind the subject out of view via rendering layers/compositing tags/etc.
Let me know if you can help!
