Animation Retargeting Doesn't Work

I’m trying to import a character from Makehuman to UE, but I am unable to retarget the animations from the default third person character to the new character. Everything is set up perfectly and the base poses match exactly, but the new animation is all messed up. All you can see when the animation is played are two giant hands flying around.

The skeleton seems ok except that when you rotate a bone you have to turn the little rotator widget around a lot more than the bone actually moves(What I mean is that I turn it 355 degrees but the leg only moves up halfway)

)

Is there any quick solution to the anim retargeting problem, or do I need to completely re-rig the mesh? I’m using Blender for rigging.

Thanks!

Exported the skeleton differently from Makehuman and tried again. The result is a bit better but still isn’t right.

Hello, this is a bone scaling issue from blender to unreal. I made a video on how I fixed it with my model listed below. You can also download my model as I give it away in the video description.
