In the map I am making I have a waiting room for a tour of a castle (no actual tour available, it's just part of the map). I have a projector screen that i put up and would like to have screenshots of my map come up on it, it will give you an idea of how to get thru the level. I'm not sure this can even be done but it would be a neat addition if I can pull it off. Basically the projector would have an env_beam or some such shining onto the projector screen. Every few seconds a new screenshot would appear on the screen and if you stand around and view it it will give you the path that you need to take to get thru. Any suggestions?

I'd first try the animated texture and see if that works in this gametype.

Thank you sir for your quick response, I will give that a try.
