What 3D modeling program is that?
Wings 3D is used for modeling, Blender is used for animating.
Can you make the player models work for Slayer/Default Bots?
That's a possibility since they are going to be playermodels after all. Im not sure If I'll be using Slayer or trying to make a custom gamemode for this.
As for bots it seems fairly easy, could even just event them to change playermodels when they spawn and some sort of coop/survival mode does sound neat. I'd call it Insanity mode or something like that after Spec Ops. Do you feel like a hero yet?
