Hello I'm a student in CG arts and this is my first attempt at using Houdini, so I've been stuck for the past few day with a issue in my simulation, I'm basically attempting to make an asteroid punch a hole through a building without collapsing the entire building but every time I'm doing the simulation no matter what the building starts to fly along with the debris and I cant seem to figure a way to glue it to the ground I've attempted multiple variations of glue constraint or pin constraint but to no avail. So I'm hoping someone could take a look at my scene and help me figure this out.

I've included the files in this dropbox link : https://www.dropbox.com/sh/k4lz2rw0settjgg/ryzKoRbtTz [dropbox.com]

Haven't looked at your file, but you can include a static object in your glue nodes' import. I usually create a sphere big enough and close enough to my geo, make it a static object, and then import that into the glue import before the glue pieces node. This should allow it to do what you need.

I don't think your collision shapes are being set up the way you intended - if you turn on guide geometry and wireframe mode and switch the collision representation to Convex Hull, you'll see what I mean.

The ‘name’ primitive attribute is used to determine which primitives belong to which object, but if you're merging the results of two voronoi fractures you can end up combining two different fractured pieces into one. You can use a different Name Prefix on one of the Voronoi Fracture nodes to avoid this issue.
