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

Edit Mode Ctrl+F Flip Normals
Btw put your trees into
doublesided group to make them visible from front and back. And put them into the
transparent group to fix the rendering.
