We performed spatial mapping using the plane manager and covered the mesh. However, due to the rendering scope of the plane manager, no mesh is applied to the non-rendered real environment.
I want to cover the space that is not covered by a mesh, but I understand that visionOS does not support post-processing and scripting shaders. They said I could use shader graph, so I looked for a way to do it, but I couldn’t implement it. I would really appreciate your help.

Is there a way in visionOS to implement this effect in real space like in a photo?
