All of the 3D skybox examples I could find for Unity were either very old or didn't include working code. I decided to build one to share. Later I will do a short writeup of what settings are required to make this work. I did use the graphics from a free skybox and planet asset from the asset store. I will give appropriate credit later in the full writeup. I couldn't upload the ZIP to the forum (too large at 52mb?) so I posted it here: http://jmp.sh/FjnqSvv Hopefully this will be useful to anyone wishing to explore this technique.
