Reproducible with: 6000.0.29f1, 6000.0.58f1, 6000.2.7f1, 6000.3.0b4, 6000.4.0a1
Not reproducible with: 6000.0.28f1
Reproducible on: macOS 15.6.1 (M2 Max), Windows 11
Not reproducible on: no other environments tested
Notes:
- The issue reproduces when the font asset’s “Atlas Population Mode” is set to “Dynamic” and “Multi Atlas Textures” is enabled
- If Multi Atlas Textures is disabled and applied, then enabled again and applied, the issue no longer occurs. However, if the Library folder is deleted and the project is reopened, the issue reappears. This suggests that there may be a problem with the import results
- It’s been confirmed that the issue also reproduces on iOS (on our side) and Android (on the customer’s side)
