Shadow artifacts are visible in between the terrains when Lightmaps are generated

Unity: Progressive Lightmapper

Fixing this would require a global stitching algorithm for lightmaps. This is not currently on the roadmap. There are ways to mitigate the issues and these have been communicated.

Reproduction steps:
1. Open the attached “1541368” project
2. Open the “Assets/_Project/Scenes/PrefabLightningScens/_ExampleTerrain_40x40/ExampleTerrain_40x40.unity” Scene
3. Open the Lightning Window (Window > Rendering > Lightning)
4. Inside the Lightning Window, press the “Generate Lightning” button
5. Wait for Lightmaps to finish generating
6. Inside the Scene View, observe the shadows between the terrains

Expected result: Shadows appear without any artifacts
Actual result: Shadows look as if cut, resulting in visual artifacts

Reproducible with: 2021.3.26f1, 2022.3.1f1, 2023.1.0b19, 2023.2.0a17

Reproducible on: Intel MacOS 13.3.1
