I have code such as the following. The performance on the Vision Pro seems to get quite bad once I hit a few thousand of these models. It feels like I should be able to optimise this somehow, perhaps using instancing. Is that possible with RealityKit in visionOS 2? let material = UnlitMaterial(color: .white) let sphereModel = ModelEntity( mesh: .generateSphere(radius: 0.001), materials: [material]) for index in 0..<5000 { let point = generatedPoints[index] let model = sphereModel.clone(recursive: false) model.position = [point.x, point.y, point.z] parent.addChild(starModel) }

Hi all, I've developed some code that enables an arcball camera interaction with my scene. I've done this using components and systems. The implementation feels a bit messy as I've got gesture code on my realityView, and then a bunch of other code that uses those gesture inputs in my component and system. Is there a demo app, or some example code that shows a nice way to encapsulate these things in to one item for custom cameras, something like Apple's .realityViewCameraControls(.orbit) If not can anyone recommend an approach to take?
