Is there a way to get access to more advanced materials rendering on RealityKit models? I want to "skin" a plane with a UIView, currently I need to fall back to ARKit and SceneKit in order to do this
RealityKit has a CustomMaterial API which allows you to create custom Metal-based materials. I’d recommend our Explore advanced rendering with RealityKit 2 WWDC talk to learn more.
There is also a great resource on Custom Shader API that gives more details on the APIs available in Metal.
