Hi, I don’t think this pack specifically solves your issue. Are you trying to remove specific individual chunks, or remove chunks that are under certain conditions e.g. chunks that have been still for some time?
If you’re trying to remove chunks that have been still, there are settings in the geometry collection under “removal” that handle that. If you’re trying to remove specific chunks, I’m afraid there’s not really a way to do that in Blueprint right now since we can’t access references to specific particles in a geometry collection. Hopefully this will change in a newer version of Unreal 5, the ue5-main branch on the Unreal github has a bunch of new nodes for accessing and applying data to geometry collections.
