It looks like the model of the building allready has many pieces which makes it kinda hard to fracture the surface the way you want.
You want to fracture the building in three pieces which is really hard the way it is right now due to that it already contains more than 50 pieces for example.
One way to fracture it into exactly three pieces is to convert the building to VDB mesh with very low voxel size and then convert it back to poly's. It should now be one solid and then the fracturing should be fine..
Thanks so much for clearing some things up. I am just a beginner in Houdini; could you please tell me which nodes to add on geometry level with winch settings? I started looking a around but cannot find anything.
Thanks!!
