Recently I’ve released Uniblocks (modular buildings constructor, inspired by Minecraft) - and all GI lighting there was done via APVs + Screen Space GI & Reflections + baked reflection probes (setting them to capture APV lighting is tricky, at least in HDRP). Rendering performance is fast enough and looks good for my use case (thanks to 0.5m wall thickness and only straight angles for walls and roof - light leaking/reflection probes rectangular area of effect - all that works very well in rectangular buildings). Some screenshots with all that:
For decent smoothness of APV lighting there is a need to set “Probes samples” value to be like from 25000 to 200000 (in scene baking options) and it is about hours to bake it for just one, not so huge, mansion
But anyway better than lightmaps :).
