Okay, so I have created a custom skybox VolumeComponent (and renderer) for HDRP after we converted our project from URP to HDRP. However - I am having issues finding resources covering also rendering meshes directly to the skybox while both supporting GI and including them in the environment reflections. I already have a mechanism which builds a spherical set of (about 20K) quads to render as stars, which currently render BeforeRefraction (Material setting). I am new to working woth CommandBuffers/VolumeComponents still - and I am wondering if anyone has seen any examples which demonstrate rendering meshes as part of the skybox. And in certain states of the game, I also need to render a custom Sun disk (on top of layered HDRI) in this component. I imagine since the HDRP Physically Based Skybox does this when rendering a planet - It would be possible with any custom mesh. My google foo seems to be failing me on this specific use case.
