Yes, you should generate the mipmaps. See also the other thread ([Unity Toolkit Basis compression - #5 by Evgeni\_Popov](https://forum.babylonjs.com/t/unity-toolkit-basis-compression/23908/5)).

Generating the mipmaps should work, I did use `toktx.exe` to generate etc1s/uastc encoded ktx2 files and it did work. Can you a provide a file for which generating mipmaps does not work?
