If I remember correctly, before the Celestia community went kaput, someone made an improved version of StarGen, after which a second community member took over and greatly enhanced StarGen even further. The last available version allowed circumbinary star system generation, large amounts of moons, and listed detailed atmosphere compositions. It was pretty cool. smile

Okay, I need a tiny bit of help here.

I moved everything over to a 0.974 installation, and everything's working okay... except I don't know how to specify planetary inclinations. What I have are much too high. I used the editor to fix it, then exported the script, but it wasn't there.

Can anybody guess what I'm doing wrong?

Never mind. I just didn't know that "obliquity" was another name for "axial tilt".

Question: Is there a way to procedurally generate dwarf moons/asteroids of random shapes, or do I have to define each one individually?

Like I said, you can also create 'DwarfMoons' with the Python version of the 'AsterBeltCreator' . As in the script that I had posted here. And of course asteroid belts!

Otherwise you have to manually create them. In this form:

Code

// DwarMoon template

DwarfMoon "Intar Stelis 4.D1"
{
    ParentBody  "Intar Stelis 4"
    Class       "Asteroid"
    
    Radius      19.3304             // km
    
    Orbit
    {
        SemiMajorAxis   0.0003      // AU
    }
}

The surfaces and everything else are then generated procedurally from SpaceEngine.

Okay. I'll see what I do with it for maybe creating a kuyper belt and some wandering asteroids. Intar system doesn't have an asteroid belt, and I coded Moko Tahna's moons manually.

Oh, wait... There's a GUI version. That'll work for me, since I don't use Python.

Oh, cool! I made an Oort cloud!



Thanks, JackDole! If I knew it was this easy, I wouldn't have been such a pain earlier...

Taciturn_Artist,
there is a brace '}' too much in this script.

You also have a typo in the 'Life' section.
It must be 'Terrestrial', not 'Terrestial'.

Code

Taciturn_Artist,
this time was missing a closing brace and a closing double quote.

Okay, what am I doing wrong here? I converted my diff (which I call surface, since it's the visible surface) into a cubemap, but it's not showing up...

Code
Surface
    {
  DiffMap        "c:\SpaceEngine\SpaceEngine0.974\Addons\Intar-Diff\*.*"
  DiffTileSize      130
  DiffMapAlpha   "Water"
  BumpMap        "Intar-land-bump.*"
  BumpHeight      90
  BumpOffset      0
  GlowMap        "Intar-cities.*"
  GlowMode       "Night"
  GlowColor      (1.00 0.90 0.66)
  GlowBright      1.0
    }

admiralsirjohn,
The path is incorrect. You can not use absolute paths.

And planet textures must always be within the folder '\textures\planets'.

You can use subfolders.

For example 'addons\textures\planets\MyTextures'.
This folder must be specified in the path: 'DiffMap "MyTextures/MyMap. *"

If you have CubeMaps, you need to specify the folder name to the CubeMaps.
'DiffMap "MyTextures/MyCubeMap"'
Without point and asterisk at the end!

The path name is case sensitive and it are slashes ('/') no backslashes ('\') in the name!
