Earth

A beautiful model of our planet with some really cool features. Add it to a completely dark scene with a single overall light and you'll see this:
— 8K textures, including a normal maps for the Earth's relief and clouds;
— Dynamic emission. City lights only light up on the night side of the planet. They can also be ignited by cloud shadows (with high shadow strength value of our overall light) or shadows from other items. The color and brightness of the night lights are controlled by _EmissionColor in the Earth's material;
— The Earth's atmosphere interacts with light and becomes invisible on the night side (you can illuminate it a little with weak light sources). At the border between day and night, it takes on a crimson hue. The main and sunset colors of the atmosphere in its material are controlled by _Color and _SpecColor, respectively;
— Auroras at the Earth's poles. They are part of the atmosphere, and their color is controlled by _EmissionColor. Keep in mind that any additional light source will immediately increase the brightness of the auroras, so you'll need to manually reduce their brightness in this case. I wasn't able to fix this bug;
— Clouds slowly float around the Earth. And just like the atmosphere itself, they take on a crimson hue at the boundary between day and night. Their colors are controlled in the same way as the atmosphere;
— Lightning flashes periodically appear in the clouds on the night side of the planet. They also illuminate the Earth beneath them (this illumination can also be visible on the dayside of the planet with high shadow strength value). The color of the cloud flashes is controlled by _EmissionColor in the cloud material, and the color of the ground illumination is controlled by _SpecColor in the Earth material.

Oh yeah, I also added the Moon as separate item just because why not.

Known bugs:
— When rotating the overall light more than 90 degrees from its initial value, city lights will disappear completely;
— When attempting to tilt the planet, the auroras will always remain in place.
— When adding a new light source, the auroras will significantly increase in brightness.
