All I did was copy the one from the Tuscany demo. It lost some of the connections so I had to figure out the order of the tiles. I'll try to create a Prefab tonight so anyone can drop it into a project.
Fantastic script, I'm sure this will be a big help to many. I've been stretching a single spherically-mapped texture along the inside of a big sphere, but even a 4K texture won't show very good detail doing that, so this script is excellent!
