I have been spending some time creating and destroying a building in Houdini but am currently hung up on a constraints problem. In my hip file I have my procedural building, I fracture it, and send the pieces to be constrained together. I haven't meticulously created the constraints yet, I just wanted to get everything in and working first. When I run the rbd sim a ball crashes through the building and blows the middle part of the building away but the top part of the building just sits there floating in the air. Not exactly sure what I'm doing wrong here, if anyone can point me in the right direction I would greatly appreciate it!
The hip file has a top level control node to cache everything for you to quickly test
