Well, the game don't crash anymore, but the weird thing is the model still doing the stand animation, even I entered the correct id for walk... yeah the model have 2 Animations in mdlvis. In modelviewer he shows me the walk animation and the stand animation, for the correct Animation, the stand animation is show in "stand" and the walk animation is show me in "walk" .but ingame it's only the stand animation. What's the Problem?
