Actually, the only other engine I've seen that I think may be even better at it than UE4 is the idTech6/DOOM but perhaps that was just from the game being pretty dark most of the time and the SSRs being used rather sparingly - or only at very grazing angles (Fresnel term). With UE4 and Enlighten we can place or modify lighting when editing or during gameplay, and Enlighten will bounce the lighting and provide reflection cubemaps in real time. In Part 2, Jay discusses his approach to photogrammetry, lighting, post-processing Reflective Shadow Maps. ini and it doesn't work. Following the Intro to Level Creation tutorial, which is going nicely. This helps prevent light leaks and flickering. 1 we were able to choose which reflection probe to use for a specific object reflections using the "Mesh renderer" -> "reflection probes" ->"Simple" menu and selecting the appropriate probe in the "Anchor override" field. Take a look at the water material and detach the specular input if it has one and then take a look.
