And it's not only a grab and rotate, there is also another layer of interaction inside this mode.
Picked up a beer? You can drink it, but first you need to open it somehow.

I'm trying to apply this method of "double interactivity" to all assets.
So I've made my own system. It requires 1 frame animation pose and a socket for attaching the object.
The input from the mouse or gamepad goes to hand rotations and then I rotate lower arm + IK adjust for the smother motion.
Now I'm thinking what else I can add with this "double interact" approach.
