Hi, I would like to setup a collision behaviour in my packed prims rbd sim.

Unfortunately, for some reason it seems that I could ignore collisions only with the ground floor, but not with other packed objects. In the example file I have 3 cubes fed into 3 separate rbdpacked objects and I would like to make it that all of the cubes interact witch each other, except one of the cubes, which doesn't interact with one of the others. I can make this cube to ignore ground plane, but not seems like the method doesn't work with the other packed prims.

I also have tried to work it out by excluding mutual affectors in Bullet/multisolver and trying to create the relationship with merge dops, but it didn't work out as well.

My student project (and me!) will greatly appreciate any help, cheers!
