Support Animation and Rigging

I’m trying to rotate the upper body of this rig without messing up the arms or the IK.

I’m not sure how to do this in Blender.

I can show what I’m trying to achieve by using Unity, which is what the model and animations will be for.

When I rotate the “chest” bone in Unity, the rest of the upper body rotates with it perfectly, I’m trying to do this in Blender, so I can animate 8 directional movement.

If I need to post the .blend file, I can.
Help would be lovely.

You basically need to parent all the upper body IK and Pole bones to upper body bone. That way where the upper body goes every thing go with it, right?
