I'm disappointed; I just purchased the pack, and after reading the comments, I thought people had managed to import them into Unreal Engine. However, it doesn't seem to work.
If only there were animations with a model... having a model, I believe, would have greatly helped with converting the animations because on Unreal Engine we can directly retarget animation from Model to another model, and the T-pose doesn't seem to be working either.
I don't understand why the author didn't include a model with it.
