This is a feature request and also a discussion on how to iterate on light building.
I’m fairly new to UE4 but I used Blender for a long time and my productivity with materials and rendering shot up when Blender introduced progressive rendering (where you can quickly have a glimpse of the final product and the image gets progressively better with time). I wish this feature was available in UE4 but I don’t know the technicalities behind game engines and whether this is possible or not. This topic was brought up in the ArchVis forum here: https://forums.unrealengine.com/showthread.php?117623-why-not-select-object-bake
As you can see from the thread, people struggle with iterating and trying out parameters when there is this huge time sink called light building. For level designers reading this, what techniques and hacks do you use to go around this?
