So in short, I have an outside and an Inside map, the outside map has outdoors lighting, skybox and so on, although the problem is that in the indoors rooms, the rooms are still being lighten up by the skybox/directional light, I’ve been trying to find a solution but I didn’t really…
Have you tried baking the Global Illumination? That should make sure indoor areas are not lit by sky and should be black. Do keep on mind that this does not affect fog colors, which you might have to override through the Volume Framework manually.
I would but the problem is that I have foliage that actually moves, if I bake the sky light or the directional light the shadows from the trees/foliage would be baked too.
I suggest fiddling with the tree prefab settings until the shadow just pops up. Do other objects have dynamic shadows? Is the light set as a “mixed light” instead of baked light?
To me it also looks like your fog settings create the illusion of light. Try disabling the fog and see if you get the result you want. If so, you need to dynamically change the fog settings as you move inside and outside.
If you don’t want the indoor area to get reflections from the skybox you would also need to add a reflection probe. You can bake it or assign a custom texture which could just be black.
