I can’t seem to find any answers on this seemingly simple problem.
Briefly, I would like environment reflections (like what a reflection probe does) per layer.
But maybe if I explain what my scene is like a little, you can guide me to perhaps a better solution.
I have a room that consists of two meshes: one for the outside and one for the inside. I would like the surrounding area to be reflected on the outside of the room but not the inside. I am using Deferred Shading and screen space reflections as well.
Reflection probes are the easiest, but I can’t get them to not apply to the inside mesh. It is also possible that I would like a different reflection to be applied to the inside mesh.
The closest I’ve gotten is to render a camera into a cubemap of the surrounding environment, and use a custom shader to apply the reflections using the normal map to the emission output of the shader; however, the problem I had with that is decreasing the smoothness on the shader didn’t blur the reflection like Unity does with environment reflections (as this doesn’t register as a reflection and a texture in the end). I can’t seem to find a way to blur the texture to make it look like it’s “semi-smooth” either.
