It’s all in the shader.

I think whats he getting at is how do you do the sky in general not just sun.

Apply a shader such as the battery sky shader to the top and all 4 insides of your box map and that will at first look all tiled and crap but when its compiled it will form the sky that you see in the battery map.

the sky shader for the battery map has a sun in it like EB showed.

If you need help making sky shaders search for it, its been covered many times on this forum.
