Hi, to open\edit a file that is already in dds format or to save them out, you will need the
nVidia Plugin.
On my system the nVidia tools work fine for saving out the various .dds maps, but tend to crash when trying to use the Normal tool, so when making normal maps by hand I use The Gimp which has similar tools out there.
Bare in mind that .dds is a lossy format, so the more times a .dds map is opened\re-saved the more detail it loses, so best to make the file in png and save as .dds map when you happy with it.
