I was wondering if we could get a reflection channel that can be used in conjunction with a sky-box, as for product animations the skybox will work like a studio and will need a seperate hdri or even png for reflections as a plain white skybox does not give good reflections.
Another thing, would it be possible to create a shadow catcher?, so that the skybox can also serve as a ground plane, in this quick animation I had to fiddle a bit to get the ground plane as close to the background as possible, still you can see the transition, so here a shadow catcher would be perfect.
