i cannot see sky....

[NaN]

Can't import it into blender for some reason. Will look into it.

I think you have to flip the skybox normals(they have to point into the box) to make it visible and add it to the skybox group.

If you check the list.txt:

Code:

#entry 65
Cube.joe
Sky.png
0 #enable mipmap
0 #enable lighting
0 #enable skybox <- this one should be 1
0 #enable blend
