I extracted CSS textures and I used texconv2 to convert from GTX to DDS. However, I'm having problems editing them. I tried paint.net, GIMP with DDS plugin, Photoshop with (NVIDIA) DDS plugin but none of them could open the files (at best, Photoshop gave me a black image in the correct size). The only thing that could even display the DDS was NVIDIA's Windows Texture Viewer, although the colour was wrong for anything that wasn't black & white. WTV displayed the format as "32 bit X8R8G8B8". Attached is an example. Does anyone know if I did something wrong extracting the textures?
