First of all I'm newbie with Unity, so please forgive me if the answer of this question is obvious for any experimented developer.
So, in one of my project I have this result while I run the project in the editor:
However, on runtime I get this result:
As you can see, several objects in the scene are no longer lighted. In fact, I noticed that ALL my static objects lost their illumination on runtime. I tried with Windows and WebGL as targets, same result.
As I'm hobbyist, I may provide any info about the project configuration. Better, I can provide the Git link of my project: https://github.com/Jeanmilost/Unity/tree/master/Survival%20Demo%20Scene
This is a demo project, but in the future I'm interested to create more serious projects, and thus I need to understand why this issue happen. So if someone can point me what I'm doing wrong, I would be very grateful, because I already spent some hours to search the solution, without success.
