MotionBuilder + Animstreet

Hello I bought a few of animations from AnimStreet. I’m trying to use those animations on a character rigged with mixamo autorigger. The problem is that the arms and the hands of my character aren’t synched with the animation. It is very strange since all other parts of my character are synched right.

Any help please ?

Try your luck with animstreet support or ask Joe McPeek from truebones animation, hes a wealth of information
