I have a scene that i'm trying to achieve where a ball slams down into the ground like a crater and after it smashes into the ground, the surrounding area slowly comes down. so in the end its suppose to look like a circular concave hole.

But i can't seem to get something right. My rbd object keeps bouncing when i smashes into the ground. i want it to sit still once it gets into the ground like its stuck there. From what i know, if the bounce value of the rbd object and my rbdfracturedobect is both set to 0, it shouldn't be bouncing right? What else do I need to adjust in order for my sphere to stop moving around?

I've also animated the distance threshold in my attribute transfer node to get the concave effect.

If anyone could help me understand why my sphere is reacting like that I would be try grateful to them!
