Hmmm...i tried 15 and its still working fine ! Ok you will have to wait A LOT if rendering the scene but with no motion it works fine...even if u animate them a little silly it still goes. So u think bluescreening would be a fine idea and then composing different layers over the original scene to get an look like army ? By the way....if u animate one skeleton..how do u extract its motion and use it on another one in the same scene ??? (Damn english is hard for me :-)))
