Directionality artifacts in multi-scene lighting setups

Progressive Lightmapper

-

Steps to reproduce:
1. Download attached project 'New Unity Project78.zip'
2. Unzip and load project
3. Open 'test' scene
4. Additively load 'test2' scene

Expected results: 'test' scenes lighting look the same
Actual results: objects have NaNs created via the additional 'unity_black' texture

Reproduced with: 2019.3.0a6
Not reproducible with: 2019.2.0b7
Regression introduced in: 2019.3.0a1

Notes:
- Reproducible just in 2019.3
- Reproduces in all render pipelines

  1. Resolution Note (2019.3.X):

    We never supported mixing scenes with different directionality settings.

    We also cannot correct for "wrong" settings, as the user might have an empty scene with some lights in it which has directionality disabled, being loaded additively onto a scene that has geometry with directionality. If we'd switch to non-directional just because some other scene is non-directional, the lighting would suddenly change in the main scene.

    I'm therefore closing this by design. The LightmapSettingsManager will warn if such a scenario is being attempted.
