UE4 Retargeting Animations for Pokemon ORAS Character Rips

[impo]

Hi all,

I was wondering if anyone has come across this problem before:

I can't seem to animate the rip of Brendan from Pokemon ORAS. 
I've tried synching the set up rig and retargeting it to the humanoid animations already in UE4, but it messes up and just gives him super big hands.

Has anyone tried using the rips in UE4 and got them to animate propery?

Cheers
