You know, you should send that video to Mindark! Those are some good looking Mobs there! GREAT work!!
More than impressed - how is it done? Animated GIFs or similar imported to some sort of movie/animation prog that enables layers or overlays ?
I know I've commented once already but shake makes me think of quake, and I'm sure some of those mobs would quake anything.
I think someone was able to extract the models and load them into a 3D package with custom animations or something (unless I'm thinking of another video)
Could be a 3D package, or some sort of movie maker. Whatever was used must have had a layers/overlay tool, but the mob animations must have taken some time just on its own, so an amazing job!
