Ok, but (I should say it in first) I thought more about, the animation of the Terminator T-800 at the end
and in the begin the T-600 without legs who attack John!

Thanks for all your reply !
I am sure they use a lot of different programs, but I don't think if they have workers on Maya they'd use too others persons working on 3DSmax !

Adapting the animations would be so much waste of time !
