This is the setup. As i said in the image thread the scene is based on my old sinkhole scene.
Very much basic as you see. Of course i used a good looking part.
It doesn't look like that in other parts
What i saw from old tests for this kind of movement using less animated parameters as possible is the best.
For me at least. Here it looked like animating the "Fractal warp shader" would be kinda enough.
Warp amount goes from "0.5" to "1" and Roughness from "1" to "0.2".
