Hey so I have this building I am trying to destroy, (REALLY new to Houdini guys, please bare with me.)

I added a scatter node, and attached that to the VoroniFracture node, and hit play, and I noticed something, there are pieces that stay frozen in space, and the pieces that do break away and fall interact with these floating pieces, giving a very broken unrealistic look.

Here is the scene, if anyone could help me fix this and maybe help explain why this happened or how to avoid this in the future, I'd love you so much haha.

I really love this program so far, want to spend more time in it.

please lock your demolitionModel File SOP, we do not have the obj file coming from disk.

Oh sorry. Here. I hope I locked this the right way.

the main problem is that you have shells, try to polyExtrude your geo, to have thickness, and try it on on one piece first
