--

-

How to reproduce:
1. Open the attached project ("1363331_2021.2.0b11.zip")
2. Right-click and Reimport "Skybox_Diff"

Expected result: "Failed PVRTC compression: Failed to launch Tools/PVRTexTool" error not thrown in the Console
Actual result: "Failed PVRTC compression: Failed to launch Tools/PVRTexTool" error thrown in the Console

Reproducible with: 2019.4.30f1, 2020.3.18f1, 2021.1.20f1, 2021.2.0b11, 2022.1.0a7

Note:
- Reproducible with all PVRTC variants (RGB, RGBA, 2 bit, 4 bit)
- Reproducible with iOS & Android platforms

Errors:
Failed PVRTC compression: Failed to launch Tools/PVRTexTool
exitcode:11
stderr:
Failed to allocate a 8192*8192 image

  1. Resolution Note (fix version 2023.3.0b5):

    Verified fixed in 2023.3.0b5.

    NOTE: after upgrading to a fixed version, affected texture(s) may need to be reimported to get correct results.

    Before: console error when importing 8192px texture(s) using particular formats, wrong results in texture preview.

    After: no console errors when importing 8192px texture(s) using the affected format, correct results seen in texture preview.
