Weird lighting

[przebra]

Im having a lighting bug related to switching scenes in unity. I’ve searched in previous posts about this but my problem looks a bit different from those
Unity version 2019.4.26

[Solved] SceneManager.LoadScene() make the scene darker... a bug?

Hi everyone, i dont want to waste your time but if you would make a test, that will take less than 2 minutes. Just take a default new scene and add a 3d gameobject with a material (not very dark). Attach the (basic) script to the GO (or wathever). The script just reload the scene when the spacebar is pressed (as you can see). Here after reloading the scene, the light (basic Directional light) seems loosing the half of its original intensity. But nothing has changed in the inspector. Same …

Lights get darker when loading scene

Basically the lighting of a scene gets affected if you load it from another scene and dont start on it. Here’s how the scene looks normally in the edit mode and playmode (if you load it first)

And here’s how it looks going through the scene pipeline

Everyone stated that this bug was not supposed to happen in the build, but it does for us! The build behaves exactly like this, the scene gets way darker

Baking the lightmap fix the bug but since we are not using baked lightmaps, we are not really prepared to do so. Doing that breaks multiple textures probably caused by UV overlapping. The uv’s only break in play mode.

So we either have to fix the uv’s or the lighting bug
