When I capture I just get a video file with like 4 boxes of me and one large one overlaying everything. I just want to put a model on this like from HL2 or something to use in my YT videos. I downloaded 3Ds Max, Motion Builder, and UDK. I just want something like this – http://www.youtube.com/watch?feature=pl ... hGHv9_3t1s – with like a transparent background so I can put it in Machinimas. What do I do?
