I would like to build my scenes with almost entirely static lighting, but our game requires you to visit the same location at multiple times of day. Is there any way to precompute multiple, different lighting bakes for a single level, or is the intended workflow duplicating a level, then loading different levels (with identical geometry) based on which lighting configuration you want?
Official solution: lighting scenarios.
I believe that’s exactly what “Lighting Scenarios” are for. They’re essentially a subset of the level streaming system, storing static lighting setups (and associated lightmaps) without storing duplicates of anything else.
Darn, that’s an entire feature I was completely unaware of; thank you!!
