Based on how I’m using the lights (adjusting them with scripts), I think they really need to be Realtime. I’ve changed the mode of all of them, behavior satisfies me.
[I am curious why everything seems to go wonky when I have more than 4 baked spots in a scene… Happens instantly if I have 4 and add/enable #5. Surprisingly, both HDRP and the default pipeline seem to have the same odd behavior. Mystery for another day, or Unity devs.]
Unity lighting is an extremely deep subject, and I’m probably out of my depth.
