The KTX specification recommends the use of a key `KTXorientation` to inform clients how to interpret the image data. However PVRTexTool seems to be generating KTX files with the key `KTXOrientation` (the key names should be considered case sensitive).

This appears to be at least one cause of this bug: [https://github.com/KhronosGroup/KTX-Software/issues/106](https://github.com/KhronosGroup/KTX-Software/issues/106)

Many thanks for reporting this bug in PVRTexTool. I have submitted issue 88479 and we will get it fixed shortly.

Thanks.
