I included some screen captures from iPisoft in this edit version of the trailer which isn't really complete yet.
Here is a copy + paste from the YT description showing off which parts I used iPisoft for: @11s Man Smoking, Man Sitting Down. @35s Soldiers Sitting and getting up @40s Getting off Shuttle @49s Security Personnel + Soldier @1m5s Security Personnel Running up Stairs @1m32s Same captured sequence from 11s
I primarily used iPisoft as a base animation, most of it is cleaned up afterwards/keyframed. Specifically their upperbodies when holding rifles or other objects for a more accurate look.
