I've been meaning to ask this for a while.

Can anyone tell me how to quickly simplify a rig? I only need the main FK bones.

I want to export the rig to Unreal Engine, and I don’t need all the extra bones it currently has. I know there’s the long method of deleting the unnecessary bones in Edit Mode, but is there a quicker way?

if you do figure it out and get it to UE, could you post it? I really want to learn in UE due to its animation controls.
