Prefab Editing Environment doesn't use skybox and light data from scene (Case 1112978)

Just reporting this issue so people are aware of it, but on macOS 10.14 and Unity 2018.3.0f2, the Prefab Editing Environment setting is broken as the skybox and light data from the specified scene are not used (nor are skybox and light data from current scene used).

Not sure if this appears on Windows, but for me it's a stable repro. So I opened a bug case for it (1112978).

 

In Windows the same, Unity 2019.1.12f1, you set scene with skybox for PrefabEditingEnvironments but in PrefabEdit there is blue background

Pretty important when you design prefabs to look good on galaxy stars skybox

doesn't work as I have autogenerate lights disabled

Uploaded sample scene that demonstrates the problem, Unity 2.19.1.12f1

 

Guess what, it somehow got fixed by itself, perhaps after unity restart

 

If anybody encounters the issue. Try deleting the "Library" folder and restarting Unity. This worked for me. It seems like the old prefab environment was being cached.
