Love Ray Tracing, love Volumetric Fog. When will they meet?
Would love to know as well!
Nothing currently in the works based on my viewings of live-streams and the UE4 roadmap.
Volumetric fog and raytracing should work together eventually, there’s nothing fundamental stopping it from happening.
Raytraced GI working with it could end up being quite expensive, but I’d imagine raytraced shadows should show up in realtime… whenever it is someone at Epic gets around to it.
