[DDS] Correct DDS Settings for DirectX and OpenGL

[aerlenkoenig]

I use DirectX and have had no problems with my mods and the textures in the game. But so that users of OpenGL can also use my mods, I now wanted to adjust the DDS files / textures, because otherwise they appear only black. (Since I have never used OpenGL, I had not thought about the DDS settings before.)

In the forum I read that the appropriate format for OpenGL for DDS files is DXT5. So I resaved all my existing DDS textures under the following settings in Paint.NET:

• BC3 (Linear, DXT5)
• Perceptual
• Generate Mip Maps
• Adaptive (Best Quality)

This worked well and the textures are now also visible under OpenGL. However, I am not completely satisfied with the quality:

DDS settings I previously used for DirectX: B8G8R8A8 (Linear, A8R8G8B8)

DDS settings I used of OpenGL: BC3 (Linear, DXT5)

Especially regarding the normal map texture of the DXT5 DDS, I am not quite as satisfied. Is this due to the settings or is there another way to adjust the quality so that it gets approximately the level of the original? I apologize if the question is silly, but I have not studied OpenGL and DirectX as well as the DDS formats in depth.

Export as .tga and use SCS Conversion Tools.
