As confirmed from @bghgary in this forum entry KTX textures are currently not handled by the GLB exporter.
As a result, the textures of the exported model remain black.
However the export seems to work if the same textures are provided in an uncompressed format as well (eg: png)
See playground example.
Repro
- Bug repro on playground:
- Expected result: Exported GLB is shown correctly with the original textures
- Current result: Exported GLB is all black
