This demo shows a technique for transitioning between two models using a field in Blender - which the title calls the “Loki Effect.”

Unfortunately for me, the explanation is in German :(
In my experience, C4D is equal to (if not far superior) to Blender, so I suspect there’s a similar functionality in C4D. And probably 35 tutorials to back it up. Can you identify the tool involved?
Thanks.
