Unanchored part destruction

Hello, I’m working on a destruction system. I’ve already implemented the cutting algorithm and a greedy mesh optimization but I don’t know how I should approach unanchored parts. Does anyone know of a good way to make sure that after the part is cut, all parts stick together and fall together as expected? I’ve heard people talk about flood-filling, but since my system isn’t grid-based I’m not sure if it would be viable.

As you can see below, the part is split in two. You would expect the top half to fall together as a single assembly, which is what I wish to achieve.

Just weld surrounding parts using WeldConstraint.

Yes use a weld to weld the object to the ground instead of anchoring it, then make sure the top chunk isn’t welded after it’s cut
