NVIDIA Texture Tools Exporter 2023.3.1 / NVTT 3.2.3 Released

I’m happy to announce that NVIDIA Texture Tools Exporter 2023.3.1 and NVTT 3.2.3 have been released!

These are bugfix releases; there are no new features, but we’ve fixed a few important bugs that were in Exporter 2023.3.1 / NVTT 3.2.3.

Bug Fixes

  • BC1-BC3: Fixes a bug in 3.2.2 where CUDA compression on Turing GPUs would produce a cudaErrorIllegalAddress error.

Thank you to adevra for reporting this bug!

  • Fixes a bug where nvtt::Surface::createSubImage() and nvtt::Surface::diff() did not copy the texture type, alpha mode, wrap mode, or normal flag from their input(s) to their output nvtt::Surface.

This fixes a bug where the ASTC preview in the Texture Tools Exporter would use the opaque ASTC compressors instead of the full-alpha ASTC compressors.

  • Exporter: If an image causes the Exporter to switch from GPU to CPU compression, the intermediate results are now fully cleared before restarting image processing.

This fixes a bug where images loaded on devices with compute capability < 5.0 would display with the wrong color space (which would resolve if the settings were modified).

  • Exporter GUI: Fixed bugs in extension autocompletion (for instance, saving a PNG image named “test” adds the .png extension if test.png does not exist).

If you spot any bugs in the new version, please don’t hesitate to contact us at texturetools@nvidia.com or in this forum. Thanks again!
