Leveraging Position Pass / UV to paint in space?

Hey all,

I'm trying to figure out a system where I can bring in a camera and perhaps some rough geometry from Max/Vray and be able to paint in the viewport and have it track over time.

I have a working system now, but I can't help but think that with a Position Pass I could make this much more elegant. As of now, I have a camera, a ground plane, and then I've had to add a number of image planes ( at varying depths because things painted onto just one plane at the wrong depth would lose their track ) that all share the same camera projection of the paint node. This works - but its messy, and not a real time saver.

I've been able to leverage the SamplerInfo/WPP from Vray to use Volume Maks, and those are amazing, but they are quite simple, I'd like to figure out how to be able to paint more organic shapes and still have it track. I don't know if this is some combination of WPP and UV, or just WPP and some node I haven't discovered yet.

If anyone has any insight I'd greatly appreciate it!
