My project involves no camera passthrough and relies heavily on sprites, but I've been discouraged from using the aging (and possibly dying) SpriteKit or SceneKit as my rendering engine by Apple engineers (here) so I'm exploring other options.
Is it possible to display 2D sprites fluidly using this framework in a non-AR context? Is it possible to create, say, a 2D platformer using just RealityKit?
A partial answer can be found in the following sample code:
Implementing Special Rendering Effects with RealityKit Postprocessing
This sort of solves my problem, but doesn't change the fact that I'm still depending on SpriteKit to render my 2D content.
