Hi Shroomly,
I’m not sure what you mean by “giving it a setting is a skin”, but…
There are some plugins for AE that let you insert 3D shapes (like spheres) into your AE comp. You can apply a texture to those shapes, and in your case, that texture might be a road that loops around the sphere. Then you just animate the rotation of the sphere (within that plugin.)
But if you don’t have those plugins, you might be able to use a bulge or mesh effect on your road animation to make the animation appear bulged outwards like a sphere.
Might be better ways…
