Ah, I see. So a 2D mask over the whole thing. I think that could work if everything was always in the box, but if I needed things to emerge the masking would get really complicated.
I'm still kind of surprised that there's not a way to do it with materials. I've done something like this in Cinema4D by applying the a background movie as a material to an object that I wanted to be invisible, but still catch shadows. I wonder if I could do something similar here? Thank you for your input on this.
