No worries at all! Feel free to ask questions any time. I’ll do my best to reply in a timely fashion
So, you might be able to retarget these anims using UE4’s re targeting tool, and then export out the new FBXs from the engine, if you don’t have access to a tool like Motion Builder.
Which character are you trying to retarget to and from? I might be able to whip up a script to help you.
Thanks!
