Hello! There is mod - that accelerates the animations in the game "Fastmod", but there are problems with it - the chance to hit in the head, etc. I've tried edit in the editor - tab animations - setting speed or FPS, but that does not give effect .. Question - Is it possible to unpack mod to see what to change in the editor and make similar mod, but without bugs. Or suggest what in the editor responsible for the overall speed of game animations?
