UV incorrect working with DDS in KSP

[Smax4455]

Hello guys. I have a problem with DDS into KSP. In Blender and Unity (in preview used DDS textures) it seems very nice (with KSP shaders), in Blender only one UV. So, I place in the model PNG textures, compile in PNG and replace them with DDS textures (how it seems), and the texture looks bad, but if I don't replace main texture, then it works as it should (but without specular). I checked sizes, and they matched. How to fix it? I really need DDS for a specular map in alpha.

KSP DDS is flipped vertically in relation to png,    if you fail to apply the right export settings, when you exported form png to dds there is a good chance the texture will be inverted . in gimp the export settings are BC2/DXT3 and generate mipmaps, for diffuse and BC3/DXT5 for normal maps ( or at least that's what works for me )

Ow, it works. Thank you)
