I have a scene and I have two different light set and sky box on one scene. It’s daytime and night time.
When I try to build the light I can only build one set of lighting.
So when I switch to night scene there are so many unbuilt objects.
Is there any way that I can build two set of lighting on one scene? so there’s no unbuilt object when I switch the day and night?
No, that’s not possible. It’s something that should be added to the engine though for exactly that purpose, otherwise you have to create two sets of the level if you want to have different baked lighting. And really it’s just a matter of having something where you can set a lightmap group that you can then tell which one to load when the level starts.
