Hello, I am very frustrated about one thing that I saw repeating over and over. Let's say you have a big and complex scene, with backed lights, and so on. When hit build, the " Auto Generate" from Lightning tab gets checked in, and overrides the lightnings with 0 backed lightning; So in the compiled game, the backed lights are not applied. Leaving everything to look way off in the final product rather in editor's "Play Mode". Before the build; Lightning settings and how the game is supposed to look. During the build: (Unity editor is Checking the Auto Generate, by itself and overtires my lightning maps) The final build looks like this: As a note: The scene is from Unity's Icon Collection, but Unity does the same thing to a lot of complicated scenes that uses backed lightning, overriding with NULL lightning data on build.
