How do I use pre generated mipmaps ?

I'm a programmer and the artist working with me is asking if i can use the mipmaps he generated by a photoshop plugin instead the Unity builtin mipmap generator. Is there anyway to use them ? Should i import as an asset and use on some kind of shader ?

Thanks in advance,

Unless you want to write a custom asset importer or post-processor in C#, the only way to bypass Unity's built in mipmap generation is to import textures as DDS files. When you import a DDS file, Unity will directly use the data from that file without any post-processing. That includes mip maps and texture compression. At least for windows, there should be some plugin to export DDS from Photoshop.
