Hi Mrfantasticghost,
I have been working on this myself and here is what I have come up with:
I set all of the origin variables to Default to the same location/rotations as the components are initially. You can get those from the Components view.
I use a timeline so that it’s a smoother transition. It would be very simple to do just and Add Local Offset, but that causes a noticeable jump. The timeline curve is just two points (0,0) and (.3,1). It is just driving the Lerp Alpha.
The Arm Location and Rotations are not needed, but I added them for effect.
Let me know if this helps.
