Unity: Graphics Device Features
Won't Fix
2021.3.X
Not backporting fixes of this severity to 21.3 LTS at this time since this appears to be fixed in later versions.
Reproduction steps:
1. Open the attached “Static Batch 2.zip” project
2. Open the “Normalissue” scene
3. Open “Rendering Debugger” Window (Window > Analysis > Rendering Debugger)
4. Select “Material” and in the “Common Material Properties” choose “Normal”
5. Observe the “beach_cliff_02_ending_left (1)” GameObject
6. Enter the Play mode
7. Repeat 4th and 5th steps
Expected result: Batched tangents are calculated correctly, same as before entering the Play mode
Actual result: GameObjects with negative scale transform have incorrectly calculated Tangents
