Light in the scene window got way brighter after upgrading to Unity 2018.2.18f1 but the game window shows light correctly

Question

So I had a project that I created using unity 2017.3 now I decided to move to Unity 2018.2.18f1 and notice a very annoying problem that I can't seem to solve, the lighting in the scene window got way too bright on the other hand in the game window even before hitting play it shows the correct light. here is an image of the issue:

I tried everything out there that worked on past versions with no results, trying removing auto generate and generating the lightmap manually, tried to change the reflection source from skybox to custom didn't work.

although in the game it self the light is correct so it didn't really break the project but it is really annoying designing levels this way

any insight on this would be great.

Answer 1

Sometimes, issues occur when upgrading a project to another Unity version. If the issue is related to lighting do the following in order:

1. Delete the lights in the current scene then create new lights. For some reason, there seems to be light issues carrying it's settings to the new Unity version and creating new lights usually fixes it.

2. Go to Windows --> Lighting --> Settings then go to the Scene tab. Scroll down and disable Auto Generate checkbox then click the Generate Lightning button.

3.Go to Assets --> Reimport All.

4. If everything above did not work, go your Project's Library folder then delete it. Restart Unity.
