-NOTES: Normal Maps don't necessarily need to be saved as DXT3, you can save a normal map as DXT1 No Alpha if you don't need the alpha channel.
+NOTES: Saving a Normal map as DXT1 does not eliminate the alpha map per se, but simply packs it as a highly compressible all-white channel.  This has the unwanted side effect of causing full specular highlighting over the whole mesh to which the texture is assigned to.  DXT3 or DXT5 are strongly recommended for normal maps.
-This will give you a smaller file, with no gloss effect whatsoever though.
 DXT5 can also function as a normal map format.  DXT3 uses an Explicit alpha map, which has a noticeable step in the grayscale gradients of the map.  DXT5 uses an Interpolated alpha map, which does not have this step and may be better suited for some situations.
