This texture was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
It's really easy to make a sphere using the frame component, but doing so makes the "size" slider break the filter and give bad results. If you need a single sphere (perhaps the even number of rows in "tiles" doesn't work for you) use this technique to get a working sphere. This technique was swiped from Sjeiti, all creative credits go to him, I just made the snippet because it took me forever to find this and it needed to be shared.
Good Luck!
