This one took me a while to figure out too.
You need to have the dds.8bi plugin in \Plug-Ins\File Formats
*and*
You need to have NormalMapFilter.8DF in \Plug-Ins\Filters
dds.8bi won't work alone, as it needs that other nVidia filter thing, with all the mad settings. (You'll see the explicit alpha option in those settings, too!)
Now personally I managed to find an older zip file with the filter in that was around 400kb(ish), and that seemed to work better than the new one. But I'm using Photoshop 6.0, so using the older one seemed a better idea anyhow...
...but I digress. So, yeah, have those two files in those two folders, and it should load just fine.
When you're saving the MIPS, remember to add ".dds" onto whatever you call the filename too. I'm assuming you're doing that already, but I'm putting it here again for posterity. So, instead of saving a MIP as "Wing", add the extension "Wing.dds" otherwise Adobe won't read it. Wordpad will try to though, and that's no fun for anyone.
You'll also find the .mat texture file in the *root* group-ship folder.
So, for the Liberty Capships.mat file, you'll need to look in \DATA\SHIPS\LIBERTY\, and it's there under the name li_capships.mat
Extracting from any other file type really won't get you very far.
Hope that helps!
