Skipping mipmaps when loading from disk

[Flone-dnb]

Hello, is there a way to skip some mips when loading a texture from disk? Consider an example where I want to load a texture that has 3 mipmaps with sizes:

• mip0 - 1024
• mip1 - 512
• mip2 - 256

but I only want to load 2 of them (skip the largest mipmap with size 1024 and don't load it into the memory) so that my final (loaded) texture will only have 2 mips with sizes 512 and 256.

I'm currently using ktxTexture_CreateFromNamedFile and ktxTexture_VkUploadEx_WithSuballocator to load textures.

Thanks.

VkUpload does not provide any control over loading only some of your mipmaps. I will be happy to accept a PR to add this functionality should your need motivate you to add the functionality.

So after spending a few hours trying to implement this feature I eventually gave up on it and just copied the loaded texture to a new one but skipped required mips. It's not a good solution but it satisfies me for now. Thanks for the info anyway.

Feel free to close this issue.
