But in the movie it looks like a multiple star system or a small diffuse star cluster:

This is a constellation or something like that.

Quote (scavenger)
the system I'm talking about is this one, right from the movie :

What? That planet is not a moon of the gas giant? It's impossible to see the neighboring planet covering half of the sky. They have again ignored physics in favor of a good picture.

Quote (scavenger)
- the main parent is a StarBarycenter (found using search F3), if I keep it as Barycenter, to find it I have to add it inside stars120k.txt

You shouldn't do this.

To add planets/suns to barycenters, you should create a second script and put in the data/catalogs/planets (and in the universe.cfg).

LOL

I know it's physically impossible to see a living planet so close to a gas giant, coz of the gravitational waves it produces, see IO for instance.
BUT.

i just want to reproduce this "system" with your game since it's possible to change the planets sizes & positions & so, without the destruction that would fatally occur IRL.

in the Osmos game, you can show the orbital trace of your sphere. when you get too close to an bigger object, the trace goes to red and change according to the real path you would follow if you don't change your route. here we have no such problems smile

so my "system" can be created, it's a matter of time before i post to you the same pictures as in the movie ^^
I'll post comparative pictures as well smile

I noticed through modding that color codes seem to come in like this:

(0.040, 0.200, 0.100, 1.000)

I looked around a bit, but can't seem to find any information on what numbers make what colors. Is there a chart somewhere, or an equation, or what?

RedKing, look on page 2 of this thread, I already answered that question there.

This is not really about creating planets exactly, but I was wondering how atmosphere models can be created/edited? I succeeded one time in 0.95 in creating and tweaking my own atmosphere model, everything worked exactly the way it looked like it should. But recently whenever I try to edit/create a model, in the engine it just turns black. Nothing I do seems to make a difference. Is there something obvious that I'm not doing to get the models to work properly?

The Bruneton's models are hardly configured. I move to the config all digital parameters, but it's still too hard make a model with parameters grately differs from default (Earth) parameters. Making Mie scattering too high produces artifact on horizon, cahnging colors produses artifacts on horizon and sunset, etc etc. These 7 models that is already included in SE is a bit tricky, the sort of good luck after hours of experimenting. I may made only onle suggestion: change only one parameter at time, and very slowly, say 1%, and control the results. Then change it by 5%, then by 10%, etc. You should check for artifacts on horizon at land level at daytime, sunset and nighttime, and the same from low and high orbit. Use locations (F6) to switch quickly between points of view.

I've done this. I have some experience in editing the models (as I said I got it to work once before and made a nice model) but now any time I try it either changes nothing or gives me a black planet. No matter what I do. It's very strange.

Specifically, if I edit the model parameters without deleting the model file, no changes are made. If I edit the model parameters and then delete the model file (so that a new one is generated) then the world is black. It doesn't make sense.

If I script for an entirely new model, then the world is black as well.

I have a problem with this. It creates the planet, but when I look away from the parent star, the planet disappears. This means I can't rotate round and have a look at the side of the planet facing the star. I'm running version 0.96, and the parent star is 'C Pup'. Did I do something wrong, or is this a general thing with space engine? Do I need to change something somewhere?

I am trying to export a planet (HD 48923 A3) but the .sc file that is supposed to appear in the export folder, isn't there. All I see in that folder are bump maps for clouds, surfaces and colors. Am I accidentally exporting the planet to some other map? Or am I simply looking in the wrong place?

You must be clicking the Export Planet option that appears when you click Editor.
You need to go Editor -> Edit Planet -> Export Script
What you are doing must be Editor -> Export Planet which exports the textures, not the script.

My star is working and in the correct place, but the planets aren't loading. It seems to generate planets just fine, so I suppose it might be in the planet script. (Star has a slightly lengthy name because I wanted to avoid conflicts with an existing, real life star). I did remove the last pair of orbital characteristics because neither this guide nor the internet states what they even mean. In one or two cases they're just commented out. I figured SE would figure them out on its own.

Posting all of them didn't work, so here's just one of them.

Code


Planet      "Ren/Asellus III"    // Type of object ant it's name
{
        ParentBody      "Asellus 45 D"  // The body, around wich this planet orbits

        //Precession      12500       // Precession period in years
            
        Surface         // Surface tag
        {
            // These parameters describes a texture pack stored on the disk.
            // I comment it out because this planet uses a procedural generation of surface.
