+'''Sidenote''': The following applies only to NVIDIA texture tools version 0.9.4. More recent versions exist. Due to a bug in handling 1 pixel mipmaps in the original (0.9.4) version, you will be further required to patch the tools with safemode's patch. The patch can be obtained here: [http://signal-lost.homeip.net/files/nvidia-texture.patch save nvidia-texture.patch file]. Patch the texture tools, compile, and install them.
 Transform your original texture using nvcompress using one of the recommended DXT1, DXT1a,  DXT3, or DXT5 formats including or excluding mipmaps (option -nomips).

 ===Validation and Testing===
 Verify the optimized texture either by opening it with GIMP (with gimp-dds plugin installed) and making sure that all mipmap layers (e.g. 12 layers for 2048x2048 original image resolution) are contained in the file, or by checking it with:
-* <code>''nvddsinfo texture_dds.png''</code>
+* <code>''nvddsinfo texture_dds.texture''</code>
 It is strongly recommended to actually test the texture or image in game before submitting.

 ==Image Naming (Extension)==
-The extension for your image file will depend greatly on three things:
+Until version 0.5.0 there were codec extensions being used for graphic files ('''png''', '''jpg''', or '''bmp'''). Unfortunately they have become totally mixed up and with the transition to DDS compressed files we have decided to move the extensions to codec-independent naming. The reason for having 2 different extensions was to help artists stick to the requirements by making them aware that there is a difference between those 2 extensions. Please note that extensions are coded in some cases so arbitrary interchange might break your graphics.
-In the future the following generic, codec independent extensions will be used:
+The following generic, codec independent extensions will be used for graphic files:
-* ''.sprite'' - for sprite files
+* '''''.image''''' - for mipmap-less 2d images (backgrounds, ui, cargo, bases, hud images and gauges, comm animations, splash screens, ...)
-* ''.image'' - for mipmap-less 2d images (ui, cargo, bases, ...)
+* '''''.texture''''' - for textures (unit textures, planet and sun textures, planet rings, sun flares, explosions, blinking lights, warp animations, engine trails, nebulae, ...)
-* ''.texture'' - for textures (units, backgrounds, planets, ...)
