Hello! This is my first bullet simulation in Houdini and I am having some issues. I would really appreciate any help I can get. I have a scene set up with multiple different kinds of materials using different kinds of constraints. Whenever I run the scene with just one type of geo (say for instance bricks) it will run and collide just fine. When I try running the sim with two types of geo (bricks and the frame) things start to explode/fall apart as if there is not constraint holding it together. I am out of ideas, as I have spent many hours trying different things. Any advice would be much appreciated!
