Hi there!

Probably it's a simple question, but I need to ask. I'm about to break an egg, but I need almost half of the egg to stay in place. I'm using RBDMaterialFracture node, and I'd like to prevent certain chunks to be simulated. Is it possible, or I need a completely different method?

Thanks

The material fracture just controls the shape of the fracture, not the simulation. There are many ways to approach what you want to do. Id probably suggest, after fracturing, group the pieces you don't want to move, then using an attribute wrangle, type i@active = 0; for that group. Then inside of the dopnet, enable overwriting attributes on the solver and specify active as the attribute you are overwriting from sops. This way, the shards you want to move will move, and the ones you don't want to move will be treated like static objects.
