I'm looking for a concept similar to unity engine prefabs. I need to have a library of objects with rigidbody that I can place in the scene. If I change original object properties (material/rigidbody params/geometry), it should apply to all the instances of this object in the scene.
linked objects. Rigidbody properties don't get linked for some reason. E.g. if I modify mass on the original, linked instances don't update.
Collection instancing. These kind of instances don't have independent simulation and just repeat what was simulated for the original collection.
