This is my sky texture : "SkyCubeMorning1+6.tga" 3072 x 512


Here is my sky definition :
sky mySky
{
layer = 2;
type = "SkyCubeMorning1+6.tga";
flags = CUBE | VISIBLE;
}

and the result is shown above. I've export the sky_gorge from
standard.wad and compare with my image file, they are the same
size and in same order.
