Override for WebGL worsens quality when using Cruched DXT Format

-

Reproduction steps:

1. Make sure that WebGL platform support is installed
2. Open project “IN-29539_LIGHTMAP issue“

3. Select “Assets\Lightmap-0_comp_light” in the Project
 window
4. Enable “WebGL\Override For WebGL”

5. Select “RGB Crunched DXT1|BC1" or “RGBA Crunched DXT5|BC3" for Format and Apply

Expected result: The file does not change
Actual result: The quality of the file worsens and the colors become darker

Reproducible with: 2020.3.45f1 (using “RGBA Crunched DXT5”), 2021.3.18f1, 2022.2.6f1, 2023.1.0b2, 2023.2.0a1


Reproducible on: macOS Catalina 10.15.7 (Intel)

Note: also reproducible with Standalone Player

  1. Resolution Note:

    This is expected, since the override switches to an LDR format. Observe that there is no significant quality difference between "Crunched DXT1" and "DXT1", or between "Crunched DXT5" and "DXT5"; it's the jump from HDR "BC6H" to LDR "(Crunched) DXT1/DXT5" that causes the quality reduction.

    Work is scheduled to investigate how to inform the user in the UI when non-optimal compression settings are used.
