After using the export to DDS, Blender freezes when closing.

blender3.6
If I modify texconv.py to unload the DLL immediately after converting the file, Blender still freezes. Idk if the dll cause the problem？
Additionally, when exporting to BC7 sRGB, the color becomes lighter even if the original format is BC7 sRGB. Only if I choose BC7, it works.

Thanks for the report.
I confirmed it on Blender3.0 and 3.6.
This will happen when using GPU via the DLL.
I mean, Blender will crash with the unloading after exporting BC6 or BC7 textures.
Idk how to fix it for now, but I'll look into it.

I noticed texconv required an option to disable the colorspace conversion.
I opened a new issue for it and I'll fix it later.

As a workaround, you can disable the unloading like this.

# blender_dds_addon/__init__.py
def unregister():
    """Remove addon."""
    for module in modules:
        module.unregister()
    # unload_texconv()

It's not a good way to fix becuase you can't remove the addon while loading the DLL.
You will get an error when uninstalling the addon after using it.
But you won't get the crash at least.

I fixed the issues. Can you test if it'll work as you expected or not?
blender_dds_addon_efad51f_Windows.zip

The crash when closing was fixed at matyalatte/Texconv-Custom-DLL@a9d196f.
The sRGB issue was fixed at 5cf72c1.
And the addon will release DLL resources after conversion. (0db4c68)

It can't export dds.

It seems the dll doesn't work?

Sorry, I updated DirectXTex to the April 2023 release. and it had a bug.
I tested it with BC1_UNORM_SRGB and BC7_UNORM when I fixed the sRGB issue.
But it won't work with BC7_UNORM_SRGB lol
microsoft/DirectXTex#378

So, I updated the library to the September 2023 release.

Can you try the updated version? It should work.

It now works with BC7_UNORM_SRGB. Thank you for the quick fix!
