Thanks for your encouragement. We’ve been working hard on this (myself, Krzysztof, Patrick). It’s really a passion for us, to bring realtime GI to the industry at a quality level that’s competitive with baked lighting while being performant enough for many use cases. It feels almost impossible at times, but then we make a breakthrough and it becomes possible again.
For top Archvis quality make sure you set Lumen Final Gather Quality 4.
Hit lighting improvements are coming. We need to fix the Surface Cache to handle small objects.
Mirror reflections on translucency will be 5.1 hopefully. We couldn’t do it in time for 5.0.
