Blender Meshes get illuminated too brightly when Directional Light Cookie isn't set to "None"

Progressive Lightmapper

-

Steps to reproduce:
1. Download and open attached project
2. Open "SampleScene" scene
3. Select "Directional Light" in the Hierarchy window
4. In the Inspector window, change Cookie to "None" (To see how bright the walls should be)
5. Change Cookie back to "cloud_cookie"

Expected outcome: The brightness of both walls in the scene view doesn't change
Actual outcome: The walls in the scene view become much brighter

Reproducible with: 2018.4.13f1, 2019.2.14f1, 2019.3.0f1, 2020.1.0a15
Could not test with: 2017.4 (Project errors when downgrading, assets can not be loaded)

  1. Resolution Note (2021.1.X):

    When using baked lighting, make sure that your second UV channel contains properly authored lightmap UVs. Otherwise, you will experience lightmap artifacts due to badly authored UVs. You can either manually author UVs in a DCC program of your choice, or have Unity generate them for you automatically in the mesh importer settings.
    Also, please keep in mind that baked light cookies are only supported in Unity 2020.1 versions and newer.
