I’m interested in evaluating the Physics capabilities of RealityKit and VisionOS. i assume that I could create Entities, add the PhysicBody Component and “simulate” and tweak settings interactively - but that’s not my experience. Is something like this possible with Beta 8?

What is the current [most recent] best practice to instancing Meshes in RealityKit? I see both MeshInstanceComponent and MeshInstanceCollection. My intent is to bind a transform to a Circle Agent (GameplayKit Agent), and feed that result to Instancing.
