[How to ] open/save NormalMaps for mods

Post by Fix » 30 May 2014, 15:32

I've seen some authors having problems with the NormalMaps in their mods.
This is because with maniaplanet, we have been using a different compression system than for TMUF : We use Ati2N compression.

But, unfortunately photoshop+Nvidia DDS plug'in doesn't open these .dds properly. That means you can't make your own normal maps directly from an existing texture_N.dds.
To work correctly, uou have to open the .dds with
the compressonator.
-Open the DDS
-File>Save Original>save as .TGA

Then, open this .TGA in photoshop, it will look like any other standard normal map. Once you are done, save this .tga as .dds (see above) in your mod folder.
(you need NVidia dds plug'in installed ):
-save as DDS
-select 3Dc XY 8bpp | NormalMap
-Image Options : ImageType = NormalMap:TangentSpace

With Gimp I use "BC5 / ATI2 (3Dc)" as compression and it seems to work fine. Edit : DXTBMP is NOT also a possibility to open .dds and transfer to Gimp (or Photoshop).

I made a small turorial (in french but with screens and the method is from CGtextures) for normal maps : http://www.maniapark.com/forum/viewtopi ... 89&t=19990
