Every time I try to retarget the Mannequin animation for a skeleton that came from All bones seem to all scale to 0 and transform to 0 or something and the output log window starts spouting this:
LogUnrealMath:Error: FMatrix::InverseFast(), trying to invert a NIL matrix, this results in NaNs! Use Inverse() instead.
here is the FBX file HERE
I have lost days of work with this issue if anyone know please help me.
