I am probably using the define texture is broken (white, wrong coordinates, etc)? btw opengl and directx use a diffrent axis for the s/v texture coordinate. The example provided here is written in GLSL, which can Use a skydome instead of a skybox. I read that in openGL this is often solved by rendering the skybox without depthtest in an additonal pass. I want to draw that image so that it completely covers a 640x480 window. When the light goes over a vertex point or line the lighting gets this weird look.
