Retargeting Mixamo In-Place Animation To Epic Skeleton

First, this script is amazing. I love it.

Second, I ran this using the Maximo default bones. Before trying to convert to UE4’s skeleton. This will be a problem, right? The only reason I haven’t converted it yet is that I’m searching for a 3D Max solution and I haven’t found one yet. Any suggestions for 3D Max users? Just trying to get my Maximo animations into UE4 through 3D Max easily.
