Summary
Since the 2019 release, Unity has provided a system for automatically generating baked environment lighting in scenes that haven’t been baked explicitly. This system is known as the SkyManager. We noticed that this system was causing confusion for our users, as the automatic behavior wasn’t very clear, and was only present in a few specific situations. On top of this, the system caused differences in the behavior of the Editor and built Player, sometimes leading to the environment lighting being unexpectedly missing.
Intend Outcome / Use Case
We are heavily simplifying the behavior by removing the SkyManager. To replace it, we’ve embedded a new default Lighting Data asset into the editor, which will be automatically assigned to newly created scenes. The asset contains environment lighting matching the default settings for environment lighting. If you change these settings, you will have to manually rebake lighting using the “Generate Lighting” button in the Lighting Window.
