I'm having problem with atmospheres and oceans on Terras, Deserts, and Titans.

Troubleshooting

What have I done wrong?

Halp! My asteroid looks unbelievably hideous,and probably not what it should look like.

Do you mean something like this? I think it looks funny.



The reason is that the surface parameters do not match such a small object.

Furthermore, Mass and Radius match not good. And the SemiMajorAxis is much too large.

Try this script.
Code

DwarfMoon "S2010 J 1/Jupiter LI"
{
    ParentBody    "Jupiter"
    Class  "Asteroid"

    Radius  1
    
    DiscDate    "2010.09.07"

    Orbit
    {
  Epoch  2455446.5
  SemiMajorAxis    0.15584670351463
  Eccentricity    0.324
  Period  1.9789608651094
  Inclination    163.24
  PericenterDist    0.10494801782593
  ArgOfPericenter    225.36
  AscendingNode    321.99
    }
}


It gives this asteroid.

For custom textures such as custom rings, where would I put them?

Hello I'm having difficulty creating a new planetary system. Basically the star does not appear where I want it to (it floats in the space between galaxies) and there are no planets.

Here is the star script:

Joe1990,

The distance (Dist) is a little big. That is deep in intergalactic space. Instead of 382 million parsecs I would turn it into 382 945 or 3829.45.

I should have mentioned that I'm using RockoRocks Star Wars Planet Systems. I was trying to get the system inside the galaxy he created. Here's an example of one of his star scripts:

Quote
StarBarycenter "Alderaan system"
{
RA 0 05 14.49
Dec 24 35 09.13
Dist 383000970
Class "G3V"
}

This code is useless:

You may remove it and smply set "Sullust system" as a parent for planets.

Tried that, it causes the sun to disappear and the words ERROR to be displayed in Type and Spectrum.

This is a very cool feature, but I'm have a few problems with it.
First, my systems seem to be ignoring the ages I set for them.
I also added some planets to Alpha Centauri, and Alpha Centauri Bb turned into a gas giant the size of Saturn.
And two of the stars in my trinary system keep disappearing. :'(

Edit: It looks like Space Engine doesn't like when you try to put planets around more than 1 star in a multiple system.
Also, how can I just remove a preexisting planet?

I have tried literally everything I can think of; it should, based on what little I know, be working fine. Everything I do either results in a star with no planets or a bunch of random planets with no stars, I even checked the log, nothing concerning my system indicates an error. I'm at a total loss.

Here's the latest planet script:

The star renders alright, but the planet is just not there.

Joe1990,

I have the StarBarycenter changed a little. Your system is now in the galactic disk.



Code

StarBarycenter "Sullust system"
{
    RA 0 05 14.71
    Dec 24 35 08.00
    //Dist 382945140.8644
    Dist  382999970
    Class "G2V"
}


But I'm not sure that it would look for you the same way.
The distance is just too big. At a distance of 383 million parsecs an arcsecond is about 1856 parsecs or 6056 light years. (If I have calculated correctly.) It is hardly possible to position an object on the distance accurately.
At this distance, the calculations of SE are somewhat random.

Thanks, big help, but how did you get the planets to show up?

As for positioning, I might ask Rocko how he did it.

Have you correctly entered the system in the universe.cfg?
This should look like this:

Code

StarsCatalogs     // stars catalogs
(
    //"catalogs/stars/Stars120k.dat"    // main star catalog in dat format
    "catalogs/stars/Stars120k.csv"  // main star catalog in csv format
    "catalogs/stars/Stars.sc"
    ...
    ...
    
    "catalogs/stars/SullustBC.sc"  // Your StarBarycenter script
)

...

PlanetsCatalogs    // planets catalogs
(
    "catalogs/planets/Stars.sc"
    ...
    ...
    
    "catalogs/planets/SullustSystem.sc"  // Your script for star and planets
)


And the scripts done in the correct folder?
StarBarycenter script in 'catalogs\stars' and the system script in 'catalogs\planets'?
