Hi, I'm new on space engine and I found how to create and link wormholes, but it only works for object in the solar system. When I want to link a wormhole to an another system he didn't work and I don't know why

I copy-pasted your script as it is in a .sc file, placed into an addons > catalogs > planets folder and it works correctly.
Here attached the resulting file.

 A new user here, it might be a stupid question but i cant find the addons > catalogs > planets folder  in my directory. Is it a space engine pro version only?

Hi, in the manual https://spaceengine.org/manual/user-manual/ there's a chapter that explains how the addons folder works, it's a must-read if you want to use scripting to create or modify planets, stars, ships, etc... The shorter version of it, if a needed folder is missing under addons, you'll have to create it manually.
As for how to create wormholes, what I posted can be used as an example or an How-To, and you can refer to https://spaceengine.org/manual/making-a ... g-a-planet and https://spaceengine.org/manual/making-a ... ng-a-star/ for the common tags used in the above scripts.

I guess the wormhole is orbiting around Saturn, with ParentBody "Saturn"? Maybe it's named "Saturn wormhole"? Then it should be available with the Find Object tool (F3) with that name.
The Horsehead nebula, being not a catalogued star but, well, a nebula, can't have an object orbiting around it as a ParentBody.
I'm sorry but it's not clear to me if you have placed a star near the nebula.
May I see your scripts for the stars folder and for the planets folder?

Hello there, how exactly do you add texture/cloud colors into the SC file? I've been trying to maintain cloud colors for an add-on that I plan on releasing eventually!

	Surface
	{
		// Surface map author: John van Vliet
		DiffMap        "Venus/Surface-JVV"
		DiffMapAlpha   "None"

		// Elevation map author: Vladimir Romanyuk "SpaceEngineer"
		BumpMap        "Venus/Bump-SE"
		BumpHeight      13.7
		BumpOffset      2.9

		// Flip the map by 180°
		FlipMap         true
		
		ModulateColor  (1.0 0.84 0.70)
	}

	Clouds
	{
		// Surface map author: "Snowfall"
		DiffMap        "Venus/Clouds-SF"
		DiffMapAlpha   "None"

		// Flip the map by 180°
		FlipMap         true

		ModulateColor  (1.0 1.0 1.0)
		Hapke           0
		Height          50
		Velocity        264 // km/h
	}

The manual here https://spaceengine.org/manual/making-a ... t-textures explains the use of the Cubemap utility to create cubemap textures. it's used for cloud textures too, not necessarily as greyscale values. If you look at the script for the Solar System, which is in data\catalogs\Catalogs.pak\planets\SolarSys.sc, you can see an example for Venus:

Code: Select all

	Surface
	{
		// Surface map author: John van Vliet
		DiffMap        "Venus/Surface-JVV"
		DiffMapAlpha   "None"

		// Elevation map author: Vladimir Romanyuk "SpaceEngineer"
		BumpMap        "Venus/Bump-SE"
		BumpHeight      13.7
		BumpOffset      2.9

		// Flip the map by 180°
		FlipMap         true
		
		ModulateColor  (1.0 0.84 0.70)
	}

	Clouds
	{
		// Surface map author: "Snowfall"
		DiffMap        "Venus/Clouds-SF"
		DiffMapAlpha   "None"

		// Flip the map by 180°
		FlipMap         true

		ModulateColor  (1.0 1.0 1.0)
		Hapke           0
		Height          50
		Velocity        264 // km/h
	}

Where even for the Clouds command there is ModulateColor ( r g b ) (from the manual: scale (multiply) the RGB and Alpha colors of the Diff texture by this value.), meaning that you can fine-tune the color of the texture.
ModulateColor can be used even on procedural clouds.
