Exospace, the DiffMapAlpha parameter in the script is case-sensitive, you should type "Water" with capital first letter.

Thank you very much smile

Hello again smile
I have a question, is there any way to change the look of a real planet without changing the code in the file "ExoPlanets.sc"?
I mean if with independent SC file, I can customize real exoplanets.
Here's an example of Celestia:

Code
Modify  "b" "HD 93083"
{
   Texture "GasGian-1.png"
   Atmosphere
   {
    Height 500
    Lower [ 0.66 0.85 0.89 ]
    Upper [ 0.20 0.22 0.22 ]
    Sky [ 0.43 0.54 0.56 ]
    Mie 0.001
    MieAsymmetry -0.25
    Rayleigh [ 0.0019 0.0023 0.0023 ]
    MieScaleHeight 12
   }
}

I don't know if a modify function is implemented, but I don't think it is. You may have to alter the exoplanets catalog, or comment out the planet in that catalog and put your version in a different catalog.

So I made a Star Called "Hydraxia" and i wanted to keep things simple when creating a planet so i created a very small code based off the ExoPlanet codes, if i'm correct this kind of code is suppose to randomly generate a planet (will paste the code) but the problem is i try to do this and the planets only show up as gas giants not matter what i do. if there is a solution to this i would like to know smile

Code
Planet    "Planet A"
{
  ParentBody     "Hydraxia"
  Mass            59.08
  Orbit
  {
   Epoch          2452899.6
   Period         0.8926405795
   SemiMajorAxis  1.29
   Eccentricity   0.231
   ArgOfPericen   94.8
  }
}

You create the planet of mass of 59.08 Earth's masses - this is obiously a gas gaint.

Buster89, a thread for discussing the creation of custom planets already exists here.

Any world exceeding 10 Earth masses will automatically be a gas world, there is nothing that can be done about it. If you want a terrestrial world, you will have to lower the mass below that threshold.

SpaceEngineer, if possible it would be nice to modify the engine to allow gas giants smaller than mass 10, etc, if forced in the catalog script. It may be unlikely or even impossible, but people should be allowed to make them for their own fantasy systems if they wish.

Yeah, I think it would be better to allow that. A chthonian planet (the core of a gas giant stripped away of its gaseous layers) could end up heavier than 10 Earth masses with a solid surface, for example.

(Is this the right place to post problems we've encountered while trying to make planets? If not, please tell me if I am allowed to move it. Otherwise, could an admin please put it in the right place?)

I am trying to make a solar system. I seem to have encountered a strange problem, however. The star (called Trollstar [still just testing things out, hence the not-so-inspired name]) is where I put it, and all parameters seem to be in order. The first planet I've tried to make (called, you guessed it, Trollplanet) simply won't appear, however. It seems to me to be a problem with the planet catalogs, but I've checked my entry in universe.cfg lots and lots of times, and nothing seems wrong there.

Here are the codes I'm using:

In data/catalogs/stars/trollstar.sc:
Code
Star "Trollstar"
{
   RA 16 54 35
   Dec -42 21 40
   Dist 2042
   Class "M0V"
   Lum 0.00017
   NoPlanets true
}


In data/catalogs/planets/TrollPlans.sc (yes, this is SpaceEngineer's example planet from the planet tutorial, with only the name having been changed):
Code

[Here was universe.cfg, but apparently the message became to long. Well, wasn't really needed, anyway.]

In particular, I do have these in universe.cfg:
Code

StarsCatalogs     // stars catalogs
(

   "data/catalogs/stars/trollstar.sc"
)


and

Code

PlanetsCatalogs    // planets catalogs
(
   ...
   "data/catalogs/planets/TrollPlans.sc"
)


Could anyone tell me what stupid mistake I've made? smile Thanks in advance.

Welcome to the forum Rtyh-12. It's probably best to discuss issues with custom planets in this thread.

First, you should take two steps to make the star:

1) Make the StarBarycenter in a star catalog (name it something like Trollsystem).
2) Then in a planet catalog, you make the star itself, and set its ParentBody as the barycenter, and give it a static orbit (see the star tutorial here, the last part is the relevant bit).

Also, don't use the NoPlanets parameter since disabling objects in your system will defeat the purpose of making it.

Fixing those issues will probably solve your problem.

Simply remove this from your star script.

Thanks for your help! Unfortunately, though, it still doesn't seem to work. The barycenter shows up as a blue hypergiant (!) of mass 0.08 solar masses (!!) and zero radius (!!!). Neither the planet I've defined previously nor the star shows up now.

Here's my trollstar.sc:

I've changed nothing here except for adding the star and changing the planet to orbit "Trollsystem" (the barycenter). As a side note, should the planet orbit the star (defined in the planets catalog) or the barycenter (defined in the stars catalog)? This is mainly for the future, since I've tried both, and it didn't make any difference.

Also, don't use the NoPlanets parameter since disabling objects in your system will defeat the purpose of making it.


For some reason, I thought it just disabled procedural planets. Thanks for the heads up!

Change this to Lum 0.00017, like in the star script. You may also remove Class and Lum from the star script, because they are already defined in the planets script.

By the way, check out checkboxes in the F4 menu, maybe you've simply disable planets smile Toggle orbits - did you see the proper planet's orbit? And what did you see in the solar system browser (F2) ?

Thank you for this info, I did what you advised me.

Sorry, but it's not that. Here's how my options look like. Also visible is the search for the star, which doesn't show any result (though the barycenter "Trollsystem", defined in the stars catalog, works).

Nothing much. Procedural planets were there, as well as a procedural brown dwarf. But my star isn't there and neither is my planet.

Thanks for the help so far!
