There's some stuff I want to do in rendering, which I SceneKit is not letting me do. So I want to build my own render pipeline.
Is there a nice way from taking geometry loaded by SceneKit and pushing it into MetalKit for rendering?
Convert SCNGeometryElement -> MTKMesh
Have you considered using Model I/O for that ?

Yes. Gone down that alley, (and several others).
How did this progress? Just seeing this many years later and it still seems like scenekit has key limitation. Is finding an offramp to metalkit a typical path?
