Quote - Thanks, ghonma. I'll have to give this a try in Poser.

So if I understand this correctly, I can quickly build a library of a few simple background props, mostly boxes or cylinders - simple stuff,  based on photos that can be tossed in easily without a lot of manual texture building/straightening etc. Things like windows, doors, paintings, that don't need to be viewed from a lot of different angles, or lit particularly accurately either. Once built, I can position these with certain limitations, but still have some freedom to move them around. I can quickly assemble little "stage props" for demo renders. These should liven up my typical dull demo renders quite a bit.

Am I understanding this correctly?

this is what camera mapping is.
