This contains a simple atmosphere shader usable on planets. I developped this for a tech demo I'm working on, so I thought of making it an addon.
- Not realistic, but fast (no nested for loops)
- Gradients of two colors for each side of the planet
- Can be seen from inside like regular fog if you want to land on the planet
- Switches to a cube mesh when seen from far away so multiple atmospheres can be drawn at lower cost
