This version only supports id-tech animations, which were made for cutscenes. Ingame anims are morpheme, may be added later.
Usage:
EvilWithin_1.exe <model> <anim>
EvilWithin_2.exe <model> <anim>
You need original .bmd6model and .bmd6anim files for this. You can extract whole game with official Luigi's BMS scripts or use modified versions included (i only added a few lines in the end so it will only extract certain files).
