Yes, the title is terrible. I could not come up with anything better.
This is a screenshot ingame "Garry's Mod", basically, I downloaded a greenscreen map, and put a Ringtransporter in (From Stargate series, transporting device) and recorded as it did it's thing.
I am just wondering, how could I be able to place something within it? Like a person or something, only way I know of is to to it with a 3D Model of the ringtransporter, then cut it in half, and have the one half behind the person/object and the other half infront, by masking the person or having a greenscreen behind him. Is it possible to do this just with this 2D footage? I have tried doing some masking in After Effects without any luck.
