I’m not sure, if someone suggested it before or Epic are already planning to add this (or already did Oo How then?).
I want to suggest a feature, that allows 3D artists set sockets right inside their 3D app and export it along with fbx. That would be helpful, if modeller doesn’t know about UE4 or doesn’t have it. So when I order a model for my game, he could set sockets right inside his app without the need of installing UE4.

Just like collision works. You set locator and give it a name with prefix SKT_ or something like that. For skeleton you should, for example, place locator as child under some of the bones.
