I have no idea.
Maybe a year or two.
The scope is unexpectedly large. 😀

In the RealityKit app I'm developing, I'm using ModelDebugOptionsComponent.VisualizationMode for debugging, but I also wanted to display other information that ModelDebugOptionsComponent does not support, like ModelSortGroupComponent draw order.

I created a hacky ECS scheme to swap in and out my own custom debug materials before and after each frame is rendered.

@theohonohan Thank you, this app looks wonderful. I will check it out.

The scene to which the action transitions.
