In visionOS, once an immersive space is opened, the background color is solid black. How do I change this? I just need to set a static color without any shading, but I can't find any documentation or examples on how to do this, and the template that comes with Xcode 15.1 beta 3 doesn't change the background color.
I've searched around for information, but all I can find points back to MTKView.clearColor, which I can't use when drawing into an immersive space, since immersive spaces on visionOS use Compositor Services and not MTKView or CAMetalLayer for drawing 3D content.
