The screenshots got double-posted. I’ve seen it in other posts, even triple posting of screenshots, and it’s probably not you or the other OPs doing it. Anyhow, I’m not sure what of those settings would be causing it. It sounds as though it’s due to the time of day, yet that’s definitely not how it should work because other lights wouldn’t be entirely non-functional / not casting light in a more realistic scenario. It’s like the skylight / directional is overwhelming the other lights in brightness to the extent those lights don’t work. One test to try is set the skylight and directional light higher up from where they’re currently located. So, change the Z value for each one to above 30000 at least. It’s possible that where they are currently is overlapping with the other lights somehow, and disallowing them from operating. That is usually what happens in the case of more than 4 overlapping stationary point / spot lights, but I’m not sure if it’s the case for sky and directional lights included.
