How to export KTX2 by NVTT3 SDK

ginokuo1974 · November 23, 2022, 3:08am

Hi, Ｉhave installed the latest Texture tools for windows
The GUI tool “Textures Exporter” can export KTX2 format.
But the NVTT SDK cannot do exporting KTX2 format.
I see there is a Container_KTX in the nvtt.h but was just commented.
Why?

Thanks.

Hi ginokuo1974!

This is something I’m hoping to fix in the future - currently the KTX I/O code is in the Exporter layer, rather than in NVTT itself. However, you can find a copy of the code we use to read and write KTX files in the nvpro-samples core library here:
