What I've also forgot to say is that it's an immersive space so we see the real world and the virtual things. So I don't only want to reflect my environment but also a virtual item onto another.

I would like the reflections to be like this. I maybe explained it wrong. It should fully mirror the texture that I have onto another texture.

Or in other words: can I create a Shader with the Shader Graph to reflect other meshes?
