Hi Rakiz,
Your script works very well. I have used it to create a modular character starting with a Make Human mesh that can utilize the UE4 mannequin/Epic skeleton and therefore many animation sequences, both free and purchasable. I have been writing a blog about my progress here: http://blog.futureofmankind.co.uk/?p=28
The only improvement I would like to see in a future version is:
- Enable the ability to Set the Bone Rolls to that of the Epic Skeleton when exporting an FBX
