OK, I want a sphere with the standard NASA unwrapped image of earth, that you can find everywhere - for example this one
I’d like to do other planets too. These images are in a 2:1 proportion.
When I attach this to a standard material as the albedo map, the result is very distorted - the poles are just tiny (Antarctica for example.)
There seems to be no way to make this thing map properly, and there is just zero documentation or information I can find on how unity maps to spheres so that I can get it to look right!
I cannot be the only person who has ever tried this before…
So, how in the world does Unity’s spherical mapping work, and how to create a texture image that will properly map on a sphere?
