The Silly Putty Image Capture Mold?

Not sure I understand the Q.
Vac forming is proabably the best, but you've already mentioned that. Dunno where the silly putty comes in.
Maybe you need to type slower so that I can understand.

Reading between the OP's lines, I think what he wants is something like the following:

After making one movie set, he wants to (cheaply) make additional copies of the same movie set, possibly by some molding process. In the molding process, he wants to not only capture (and duplicate) the shapes of the original set, but also any imagery on those sets, e.g., the colors and so forth (possibly including painted or similar images) on those objects.

The intent then is to allow him to, during shooting of the movie, destroy copies of the sets, but still have additional sets to reshoot should the need arise.

The reference to silly putty is the old silly putty property of capturing an image from a printed page--press some silly putty onto, for example, a printed comic strip (in the newspaper), peel off the silly putty, and you've captured a (mirror-image) copy of the cartoon.

I'm not involved in the movie industry, but I think there are techniques to minimize the need for multiple copies of the same set, probably including green or blue screen techniques (i.e., shooting actors / actions against a blank colored screen, then superimposing those shots over separately captured shots of the background.

Also hiring very good / experienced special effects people who can do a good job of predicting how a set will look in the process of being destroyed, and capturing that destruction with multiple cameras / povs.

BTW, I don't know of anything that would do what the OP requests, but it's not an area I have any expertise in. No doubt the size of the sets would be important. It's probably impractical to mold a copy or the (real life size) Empire State building for use as a movie set. ;-)

Essentially you are correct rhkramer as concerns what I was wondering about.

"or" in the penultimate line (I get paid extra for big words) should have been "of"
