As for the flipped textures, there is a flag in the WLD header that denotes if the zone is old or new. I assumed that would allow us to flip or not flip the texture across the y axis. Unfortunately, the classic and the titanium Greater Faydark both say they are old zones so it won't be that simple. My next idea is just to check the bit depth on the textures when they load. If the depth is 8 bit, we know it's a classic zone and 24 bits, a newer version zone. Again as I mentioned, I will be learning shaders for the next week or so and then I am going to tackle both per vertex and per pixel lighting in GLSL.
Awesome work Tabasco.
Cheers!
