I made a US soldier mesh by importing the vanilla US model. I unbound the mesh from the skeleton then I selected the mesh and clicked on mesh>sepereate so I can remove the WW2 helmet. Then I replaced the helmet with a new one and selcetd all meshes to combine them again. After that I selected the skeleton and the mesh and clicked on skin> bind skin. I then exported the model and everything seemed to be working fine. But the model always explodes just for the charging animation called GER_infantry_charge_rifle.anim Does somebody know why this is happening? I think it's because I have to bind the the mesh and the skeleton differently but I am not sure.
The linked image shows what happens when model goes into that animation
