| I'm trying to load a gas giant but I can't change the colors and the aurora doesn't show up. Perhaps I don't have an understanding of how colors are defined, but I kept changing the values and nothing happened. It stays a gray planet with a bit a red shading. Finally, I set the surface values to what SpaceEngineer had in his planet tutorial and it didn't look anything like the planet he got. It stayed exactly the same.
I cleared my cache everytime I tried this.
Also a sidenote: I want to change the temperature without the "greenhouse effect". What parameter do I add to atmosphere? I couldn't find it anywhere.
Thanks.

| Enki, you may found that planet tutorial is for SE 0.95. Many parameters are changed since. You may use planet editor instead of creating the new script. Just found a planet you like to change, open editor, change parameters and export the script.
Quote (Enki) Also a sidenote: I want to change the temperature without the "greenhouse effect". What parameter do I add to atmosphere? I couldn't find it anywhere. Only Greenhouse parameter affects temperature. If you do not satisfy with it, you may change albedo of the planet, change its distance to sun, and change sun's luminosity.
Also, you may need to read the forum rules and find appropriate thread to post your questions instead of making a new one.

| Sorry if I posted in the wrong forum and thanks for the advice.
I couldn't find any options to change the color in the planet editor, but when I exported the script, I found several options that look like they should be for small, solid planets but the gas giants must generically use anyway. Now most of my gas giant is red. I will continue to tweak this and see what I get.
Thanks.

| Gas giants just uses the same parameters for coloring the cloud layers. Just think of them as elevation (colorSea - bottom layer, colorSnow - topmost).
