Official [2020.1] New Feature - Lighting Settings Asset

I keep having lighting settings assets randomly generated in my 2D project that doesn't use lighting. Is there any way to prevent this from happening? It didn't happen before I upgraded to 2020 from 2019.

 

I just had to assign null to the lighting settings asset (and bump the serialized version to 12) in 213 scenes when upgrading from 2019 to 2020. The upgrade path here wasn't handled very gracefully, I don't think. I'm not sure that Unity realises probably 99% of all unity developers just want a global "I'm not even using basic lighting, so just turn all that off, thanks" option.

 

Bumping this. How can we turn this off? I am not using lighting and would like to turn this off by default so a .lighting file is not generated everytime a scene is modified.

 

I found a "workaround" that's alright for me: click "New Lighting Settings" but then when the new file comes up, click ESC. It seems to then save the lighting settings inside the scene file or something, and no new .lighting file is generated.

 

Hey, yeah; updating from 2019 LTS to 2020 LTS. How can we turn this irritating behavior off without per-case workaround? We have a 2D project that does not use lighting, with hundreds of scenes and I don't want this cluttering up the project with useless assets every time I work on a scene.

Can't we just add a *global* toggle in Project Settings for not generating these assets instead of having to go to the lighting tab for each and every one?

 

Working on a 2D project here as well and the lighting settings file generated is more annoying than anything. I know I can just delete it everytime it pops up, but is there still no option to turn it off? I'm using version, 2021.3.8f1

 

I am also experiencing this problem after upgrading from 2019. What I tried was assigning null to the LightingSetting when the scene is saving, and it worked.

Code (CSharp):

1. using UnityEditor;
2. using UnityEditor.SceneManagement;
3.  
4. using UnityEngine;
5. using UnityEngine.SceneManagement;
6.  
7. public static class SceneSaveHook
8. {
9.     [InitializeOnLoadMethod]
10.     static void Init()
11.     {
12.         EditorSceneManager.sceneSaving += OnSceneSaving;
13.     }
14.  
15.     private static void OnSceneSaving(Scene scene, string path)
16.     {
17.         if (Lightmapping.TryGetLightingSettings(out var settings))
18.         {
19.             Debug.Log($"Set Lighting Settings to null: {path}");
20.             Lightmapping.lightingSettings = null;
21.         }
22.     }
23. }
