Failed writing Precomp Packed Geometry file with a terrain that has low realtime resolution
Reproduction steps:
1. Open project attached.
2. Load scene "Scene"
3. Open Lighting window.
4. Press build.
Expected result: Lighting will be built without any problems.
Actual result: Lighting can not be built errors appear:
Failed writing to: 'C:/Users/se/AppData/LocalLow/Unity/Caches/GiCache/f4/f411a9d8d2a5add29291c3258556d6f3.ppg.tmp'.
Error: 'Failed writing Precomp Packed Geometry file.' - Mesh: 'New Terrain'
Notes: This problem only appears when having 4097 heightmap and precomputed realtime GI is lower or equal to 0.1
When precomputed realtime GI is higher, everything works fine and there is no errors.
Error "Failed writing to: 'C:/Users/se/AppData/LocalLow/Unity/Caches/GiCache/f4/f411a9d8d2a5add29291c3258556d6f3.ppg.tmp" appears every 5-10 mins.
Reproduced on: 5.4.0f3, 5.5.0f3, 5.5.1f1, 5.6.0b5.
