| Ever wanted to add city lights to your planets but can't deal with exporting all the textures? Here's my solution.
1) Open your planet system's file and open the file.
2) Scroll down until you find something like this on your planet:
Code // these values are randomized!
volcanoMagn 1.1064
volcanoFreq 4.03961
volcanoDensity 1
volcanoOctaves 0.581479
volcanoActivity 1.945364
volcanoFlows 1
volcanoRadius 1.3567
volcanoTemp 2054.03
4) Once you found it, replace it by pasting this in:
Code // results may vary depening on the size of your planet
volcanoMagn 0.25
volcanoFreq 25000
volcanoDensity 1
volcanoOctaves 1
volcanoActivity 1
volcanoFlows 1.075
volcanoRadius 75
volcanoTemp 4000
Once finished, save it and open SpaceEngine. You'll (hopefully) get something like this:
Some cons of this are that the surface of the planet look like this:
Also, performance drops, small range of colors (red->white->blue), so this isn't a great option, but I found it cool.
Have fun with this!
Recommended for RC2 only.

| Is there any way to make it so that the lights distribution doesn't show as giant rings circling across the whole planet, like in the first screenshot?

| PlutonianEmpire, I don't think so. Although, I kinda like the ringed lights around the planet. It makes it seem like an advanced intelligence. But I don't know, that's my opinion.

| Well it would work for planets like Coruscant from Star Wars. 
Also, I noticed something cool; if you add GlowMode "Night" to the procedural surface parameters, it actually makes it look like bioluminescence!

| Another method to generate night lights, is this:
Code Clouds
{
Height 10.0
// City lights map author: Sean Young "HarbingerDawn"
DiffMap "Earth/Lights-HD"
DiffTileSize 258
DiffTileBorder 1
GlowMap "Earth/Lights-HD"
GlowTileSize 258
GlowTileBorder 1
GlowMode "Night"
GlowColor (1.00 0.90 0.66)
GlowBright 1.0
Velocity 0.0
}
I use cloud layers.
Here I use the night lights of the earth.
Not quite suitable to my planet, but they show what I mean.
Don't forget to look here.

| I found a way to change the colors (a bit)!
If you set the "volcanoTemp" tag to 1000000+, like this;
Code
volcanoMagn 0.25
volcanoFreq 25000
volcanoDensity 10
volcanoOctaves 1
volcanoActivity 1
volcanoFlows 1.075
volcanoRadius 75
volcanoTemp 1000000
then the lights become pink!
Also, I found out that different atmosphere models ("Titan" is more noticeable) or classes of stars also change the colors of the stars.
Cities with "Titan" atmosphere model:
Cities around redder stars:
You can also usePlutonianEmpire's idea to of adding this make them even more city-like
To answer this question, I also figured out that editing these values can remove the ringed look.
Code
volcanoMagn 0.25
volcanoFreq 25000 // can be edited
volcanoDensity 10 // can be edited
volcanoOctaves 1
volcanoActivity 1
volcanoFlows 1.075
volcanoRadius 75
volcanoTemp 1000000 //blue to pink

| You can also use GlowColor variable alongside temperature variable.

| I've tried that, but it only works on non-procedural surfaces.

| Can confirm, I've tried as well with no luck.

| Are you able to get it to work on moons as well? I've tried your code on three different moons and they all came out completely green on the nightside.

| So, now I'm surprised how much inhabited the icecap of my main world An'Cheadhain is.
Presumably there is drilled for oil, and searched for other natural resources.
And I really wanted an ecologically correct world! 
Don't forget to look here.

It works on all worlds as far as I can tell.

Is that from the Irish language? It looks very like it.

| Interesting. It may be my Intel HD card acting goofy again.
What I have been seeing is that each and every single moon that I give the "city" lights code, even though the code is exactly the same as tye code you posted earlier, show up completely or almost completely green on the night side, like this:
Here's my log files and planet scripts. I'm using RC 2.
