Mr Obihb.
Thank you for your time once again about this. I searched around CatRig documantation and I have found something called “Motion Extraction Node”. I fiddled with it’s limitations abit and was able to make it behave like a Root Motion bone.
The only thing I get is a fbx warning in 3dsmax, but it does not effect anything in UE4. If you want I can give more information about it.
Regards.
