Just to dribble a random thought or two on the carpet, while at it anyway: Have any of you played Skyrim in VR? -In a few places in some dungeons the level designers have added detail/depth decals to stone walls and floors, and maaaan does having those infinitely thin stencils floating a decimetre over the muddy surface below look terrible in VR...
...then you have something rather
nice, that can be seen in both that game, and Elite: Dangerous: I wonder whether the "depth look" one can see on scatter rocks on icy bodies, is a simple matter of the objects being modelled with an inner "stone" mesh encased in an outer "clear ice" one, or whether that is a shader trick on a single shell, and where the postponed volumetric effect ice shader, falls there, as well as how much juice it guzzles... :7
