Well, I can resave them with mipmaps. In flightsim world mipmaps for player aircrafts usually useless, since the aircraft is always near player and camera. Mipmaps are used for scenery objects and AI aircrafts.

The mipmapping is used for high view angles too and without mipmaps the result is shimmering on contrast parts of the texture like texts and numbers. The good example is the UDN skin and the view from behind. I am using anisotropy 4x for all object textures so there is no blurriness when mipmaps are there...

Ok, I'll update the textures. What settings are better to use?

BTW, can we have possibility use not only DDS format, but PNG also for textures? DDS are very user-unfriendly. It could be done like in x-plane, if there is DDS file, xplane uses it, if theres only PNG with specified name it uses PNG.

Why unfriendly? The reason for the DDS as the only format is the performance because this file can be directly uploaded to GPU memory and the PNG format has to be unpacked and converted into DDS and then uploaded or converted on GPU side but it means larger transfer through PCIe bus. But I was thinking to add conversion from PNG/TGA to DDS into import tool later.

I am usually using command line nvidia texture tools
http://code.google.com/p/nvidia-texture-tools/
plugin for photoshop: http://developer.nvidia.com/content/nvidia-texture-tools-adobe-photoshop

nvcompress -bc1 for diffuse textures (DXT1 format)
nvcompress -bc4 for opacity textures (ATI1 format)
nvcompress -bc5 for normal maps (3dc/ATI2 format)

it automatically generates mipmaps...

I have very strange graphic issues using nvidia dds plugin for photoshop when it saving file. And the saving time is very big, comparing to png

PNG's lossless compression can be sometimes more efficient but GPU can't use it... And the final size of the DDS file depends on the used internal format (compression ratios: DXT1 1:6, DXT5 1:4,  RGBA8 1:1 ). PNG is good for storage because it is lossless, DXT1,DXT5,ATI1,ATI2 are lossy formats and usually their quality is much worse than JPEG with the same size...

A PNG importer tool would be very helpful for us noobs that want to do all our skinning in MSPAINT.

Would there need to be multiple PNG's for reflection layers and such?

If I remember correctly you can use DxtBmp tool. You can find it on this site: http://www.mwgfx.co.uk/
With this tool you can open DDS file, export it to PNG/JPG/etc., import JPG/PNG/etc. and save it as DDS, also you can choose path for your graphics editing tool (e.g. GIMP or Paint :P) then you can skip exporting and importing steps if you want to edit textures. ;)
