After clearing baked data Skybox Environment Lighting stops working, the scene gets dark.
This issue is only in Unity 6 (6000.0.34f1), in Unity 2022 it works fine.
This is expected behavior. Previous versions of Unity would constantly re-bake environment lighting automatically, if no manual bake has been performed. That behavior was changed after Unity 2022. Now you have to bake manually. Just press Generate Lighting and the environment lighting will reappear.
How anyone sane could design this as expected behaviour? So… lets say i want to clear all lighting to its default state. How should i proceed? Because clearing baked data (which was intuitive enough in previous versions) is clearly not working
