Relation to NVIDIA Texture Tools exporter

[ShukantPal]

Is this software the same as this: https://developer.nvidia.com/nvidia-texture-tools-exporter? Thanks for the clarification.

Unfortunately, no. The closed source nvidia texture tools are probably based on an earlier versions of the open source nvidia texture tools, with additional changes that are not public. I know that's really confusing, but I don't work at nvidia, I don't have any control over what nvidia does with their tools, and why they chose to discontinue their open source efforts.

From a cursory look at the DXT1 compressor, the performance is good, but quality is mediocre, which is unfortunate. The BC6-7 compressors are hopefully better, the open source codecs in NVTT need a lot of work to be useful in practical scenarios and you are probably better off using Rich Geldreichs (https://github.com/richgel999/bc7enc) or AMDs compressors (https://compressonator.readthedocs.io/en/latest/developer_sdk/cmp_core/).
