What’s the easiest way to add user interactions (pinch to scale, rotation, transform) to an Entity loaded from a local USDZ file in RealityKit?
You can use the installGestures function on ARView. Keep in mind that the entity will need to conform to HasCollision.
To do this you could create your own CollisionComponent with a custom mesh and add it to your entity or you could simply call generateCollisionShapes(recursive: Bool) on your entity. Putting it all together, you can use .loadModel/.loadModelAsync, which will flatten the USDZ into a single entity. Then call generateCollisionShapes and pass that entity to the installGestures function. This will make your USDZ one single entity that you can interact with.
