I want to add a gobo effect to a spotlight in RealityKit. I looked in all information, but I could not find support for it, while I saw that it is supported in SceneKit. However, I can not use SceneKit in combination with the RealityKit application I was already writing, and it would be a lot of effort to go back to SceneKit. Is there a solution to or add gobo effects for spotlights in RealityKit, or use the combination of RealityKit and SceneKit in an AR application?

Is there an example on how I could perform relighting the real-world using RealityKit (or SceneKit or ARKit if possible)? What I mean is thatI would like to use lights in the virtual world to shine on objects (or using depth map) of the real world. thanks
