In order to keep the code small and reduce maintenance costs we have limited the
features available in our new texture tools. For this reason, we have also open sourced the code, so that people can modify it and add their own custom features.
NVIDIA has a license of the S3TC patent that covers all our products, including our Texture Tools. You don't have to obtain a license of the S3TC patent to use any of NVIDIA's products, but certain uses of NVIDIA Texture Tools source code cannot be considered NVIDIA products anymore. Keep in mind that the NVIDIA Texture Tools are licensed under the MIT license and thus are provided without warranty of any kind.
