With this PR screen-space refraction is functional. Caveats: The blur passes for supporting rough refractive materials is quite heavy and increases with the resolution. SSR uses a gaussian approximation for the brdf and therefore doesn’t match perfectly cubemap-based refraction and IBL. The use of MSAA with screen-space effects, while working, is going to incur a large cost, especially on tilers.
