Light through glass materials, Raytrace?

No problem! I think I remember reading somewhere that making raytraced glass a lot better is coming on the roadmap somewhere in the near future, though I can’t remember where. Another limitation of raytraced glass to keep note of are that refractions using raytracing don’t take into account the shadowed skylight OR global illumination, which can lead to things viewed through a glass object looking super washed out and flat.

A while back there was a cool UE4 build that had some AMAZING real-time caustics for raytraced glass: Generating Ray-Traced Caustic Effects in Unreal Engine 4, Part 1 | NVIDIA Technical Blog. This makes me optimistic for raytraced glass in future versions of Unreal.
