Yeah it sounds like that might be a solution for simple objects, but for what I have in mind it would probably become pretty unwieldy.

So it sonds like the solution right now for stills is to do what PAQ did, and do a render overlay by matching up the MOI viewport with my Modo camera.

For animation it sounds like I am out of luck, unless I can find a .skp importer for modo that will import the poly lines.

Again thanks for all your help.
