3d circle map

[SacharM]

Hi everyone,
does someone have a solid experience with Rayshader? I want to make a similar one but for my home city. But have no idea, where to start. It would be amazing if someone could make a complete and detailed video tutorial for beginners on bringing any city map to Rayshader. This is a small piece of information an author provided on Reddit:

the trick is to make a globe with very thin walls using two spheres, one slightly smaller than the other, with the index of refraction of the smaller one set to 1 (empty space).
