Is it possible to set a CALayer as the contents of a RealityKit material? Currently this is possible with SceneKit materials. I am wondering if there is something similar for RealityKit. https://developer.apple.com/documentation/scenekit/scnmaterialproperty/1395372-contents

Does Metal support utilizing the ray tracing acceleration hardware available in the Radeon 6000 series GPUs? Can the 6000 series run the WWDC20 session 10012: Discover Ray Tracing with Metal demo? Do any AMD GPUs support it or only the Intel integrated ones? The WWDC session video shows a sample forest scene running on a Mac Pro with the W5000 series AMD GPU.
