| Hi, sorry if that is asked already:
- Would it be possible to add new galaxies and nebulae models in the galaxy and nebula model.cfgs to be used as procedural galaxies and nebulae and not affect numbering of procedural systems?
eg I have all Voekoevaka's galaxies added to galaxy model.cfg (together with their appropriate entries in galaxies10k.cfg) and have ''UseForType'' command in model.cfg enabled because if it is disabled that particular model will not be used for procedural galaxies afaik, but then all numbering of procedural stars in catalog galaxies change and I can not share a location I find because my SE universe is different from the ''clean'' SE universe with no addons.
In short: It would be great if we could add add-ons like new galaxies and nebulae to be used both as catalogs and procedural objects in SE but without affecting the numbering of procedural systems in catalog galaxies and ideally in procedural ones as well.
- 3D planetary rings should be possible because many othe spacesims have them e.g. Elite: Dangerous. I think they are using a technique where the same pattern of rocks is used again and again with some randomization so it doesn't look too repetitve. Also the rocks don't move in orbits - they only roatate around their axis in a similarly random pattern to give illusion they are moving. So if a similar techique is used for SE I think it would not require a supercomputer and should be doable. The trick should be to make SE think that all these rocks are one object (or at least a small group of objects) and not millions of objects. If this works then the possibility of having stars rotating around galaxy will not seem so impossible <--- probably wrong analogy 
sorry if this is suggested before and for long post

| Nebulae models does not affect the numbering. But galaxies models of course do, because changing the texture of the galaxy will change the shape of spiral arms, and because the star generator takes them into account, it will generate completely different galaxy. There is no way to bypass this problem, except ignoring the actual galaxy texture, but this is not a solution.

Space Engineer thank you very much for your reply!
Ok, understood but this should only affect the stars of the galaxy that the new texture refers to. Why does it affect the seed of all stars of all galaxies i.e. af all universe? For example if I add voevoevaka's galaxies, the numbering of Milkyway stars is also changed.
Sorry to ask too many questions...

| Quote SpaceEngineer ( ) Didn't read all, I'm too tired now
Thanks for taking your time to answer me
Okey, by parts:
So Submoons, Circumbinary moons, asteroid moons, double asteroids, double moons and moons around the components of binary planets are imposible by now, but from what you said I infer that all of this amazing features will be implemented at the same time when the system architecture is changed no? Please, that would be amazing
Quote SpaceEngineer ( ) Asteroid rings could be added easily.
oohhh that's great!!!
Quote SpaceEngineer ( ) Also, the Solar system browser would be hard to use, if the system will have 100+ planets
But is necessary to change that right? I mean, maybe beyond the version 1.0 we could se that? Because that would be awesome! and relistic also.
Quote SpaceEngineer ( ) Planets with extreme orbits cannot be implemented easy, because generator can't "clean out" their neighbourhood off other planets that intersect their orbits.
Oohh I understand. The issue of the planetary orbits with high inclination respect to the plain of ecliptic woudn't necessary intersect any planet but I comprehend the problem. Well, I only can say that if that problem is overcome one day it would be a giant leap also and would add much more variety to the experience. I see comets in SE that are in high eccentric inclined orbits but a planet with that kind of orbit is to much strange to be added maybe. Wow I would love to see this kind of changes!!
Quote SpaceEngineer ( ) Real KBO catalog is already included in SE
Thanks a lot for the instructions
My part of the work
Quote SpaceEngineer ( ) Is that documentary on English available?
I've searched for the docuementary in other languages but I couldn't find it. What I could found is the papers and the researchers upon the issue of excentric giants is extracted the information in the documentary.
And I'm going to explain that in the next post, because is quite interesting and maybe with that you could get inspired on how to do the coding

| The naming is based on galaxy number in the array. It change if you add or remove a galaxy from the catalog. It didn't change if you change the galaxy model or texture. But the seed used in the procedural generation is based on coordinates, not the name or number in the array. It changes only if you change the galaxy coordinates.

| Hello everyone!
I hope I am in a right tread for my following question/suggestion?
In one of the following updates (0.97.2...), is there maybe going to be a way to control your spacecraft in a same manner one controls the camera in "spacecraft mode"? So any ship imported or the default one could be controlled in the same way you control your camera in "spacecraft mode". Giving us a possibility to adjust the acceleration of the ship with the mouse wheel and with the benefits of rest of the Newtonian laws that "spacecraft mode" offers  .
Maybe there is a tread or a suggestion like this somewhere on this forum, but I could not find it. If not here is one. Maybe someone can even make a mod for current version (0.92.1) that just attaches the ship model onto the camera? In my opinion I think this would be seriously fun user experience.

You can already do this. Open the console (~) and type "UFO". This will allow you to control the spacecraft using WASDRF, and using mousewheel to set any desired acceleration. You can also type "aero" and "gravity" to disable aerodynamic and gravitational effects to make it behave exactly the same as the camera mode.

Thank you Harbinger!
This is exactly what I had in mind. Another level of fun in this amazing program.

| Quote FastFourierTransform ( ) Eccentric Jupiters
First of all, they are not so common. Usually hight eccentric orbits reduces to almost circular when additional planets discovered around the star. So this effect is a lack of knowledge of full architecture of the system. Also, you have written: 7% of all stars, where planets have been found.
Quote FastFourierTransform ( ) Inclined Exoplanets
As you have noted, this is relatively common only for hot jupiters, and explained by planet-planet scattering, the mechanism responsible for the hot jupiters formation.
Anyway, hi-eccentric and inclination planets should be of course, and the will be implemented in the new system generation code. Not in 0.972 though.
Quote FastFourierTransform ( ) Trojan Planets
Actually, trojan points are semi-stable for planet-size bodies. They are stable only if the body have negligible mass compared to the star and main planet (ie asteroid), but this is not true for full-sized planets. The Tethys and Dione have asteriod-sized trojans too. Trojan planets can exist in young systems though - even Earth had a trojan planet Theia what had collided with Earth (due to instability of such configuration) and formed the Moon.
Anyway, you made a good research, thanks for links. On the Russian forum, I have a special thread where I collect links to articles related to planetary system architecture, formation and evolution. i am periodically refer to it when I made changes in the solar system generator code. If you have a account on the Russian forum, I would ask you to copy your post there, to have all in one place. Otherwise I can copy it myself.

It can be stable for full-sized planets, it simply depends on the relative masses. A small planet like Mars could not have a stable trojan planet, but gas giants could support relatively large trojan planets and still be stable (at least, this is what Watsisname determined here).

| Would the community compiling a list of catalog stars with wrong spectral classes (the giant orange and red dwarf stars) be any use to SpaceEngineer?
I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

Aahh, okey, I understand, good point. But beside that I think there are quite a lot real eccentric planets. And there are many many mechanisms to explain eccentricity excitations in the formation of planetary bodies (as well as eccentricity damping as you have mentioned). Here you have some very recent theory about how the eccentricity can in fact appear with varius mechanisms.
Quote SpaceEngineer ( ) Anyway, hi-eccentric and inclination planets should be of course, and the will be implemented in the new system generation code. Not in 0.972 though.
I would love to see that. Can't wait.

Thank you. I don't have an account on the russian forum and I know very little of your language but if you want to copy paste this I would be very very ammused.
Thanks for the work.
I think that when you change the system generator we are going to have a great Space Engine revolution (interplanetary Objects, Intergalactic Objetcs, Trojan Objects, Eccentric orbits, Highly inclined orbits, circumbinary orbits on planets and moons and rings, etc...)

| This night I dreamed with the 0.9.7.2 release hahahahahahaha I'm getting crazy (I have no hurry in this but I think a lot on space when I go to sleep). The dream was not so amazing but I remember seeing rings around asteroids like Chariklo ect...
One of the things I saw is what I want to propose por Space Engine (even with the lack of proper references and calculations). I would be very glad to hear what all of you think about the idea (and i'm asking Vladimir about the feasibility of this for the next version)
Lava Rings
In planets, sufficently close to their stars to melt rock and sufficiently far to allow to a ring system to exist (maybe in small mass, but very hot and bright, stars) there should be "lava rings", formed by a glowing flow of small incandescent particles, and melted debris in orbit. The rings would have some kind of redish glow. The part in shadow (by the eclipsing planet) would have some gradient of brightness and black body colour shift to the lower temperatures (because the dissipation of heat in the night side would freeze the melted small particles rapidly). The minimum of brightness would be in the frontier of exiting shadow, and the the temperature would rise again rapidly creating another small gradient in that zone.
The lava ring in shadow would have also a radial component of the colour-brightness gradient: the inner parts of the ring would transit the "cooling zone" created by the shadow more rapidly. Perhaps so fast that this part of the ring system would be perpetually glowing, but the farthest part of the ring would cross the shadow with so many time that the particles would stop glowing at some point.
The inner part of the lava ring, because is closer to the planet surface and because it's hotter during the transit in the planetary shadow, could maybe illuminate some equatorial latitudes of the planet's night side. I haven't done any calculations but I suppose that the equator woudn't be so bright because the lava ring would apear in the sky only like a fire line dividing the celestial sphere at night (and would occult the rest of the ring). Instead, on higher and lower latitudes, near the equator, the glowing surface area of the ring would appear bigger in the sky, so the landscape in those nigh side latitudes would be more illuminated. There is probably a latitude with the maximum brighness because near the poles the brighness would start to decrease again due to the atmospheric extintion (because the glowing ring would appear in the horizon) and due to the higher distance to the ring. So the night side of the planet probably would look like two fringes, equally separated by the equator, of redish ambient light.
I was thinking also about seasonal changes. In the equinioxes (refering to the moment when the star is in the same plane of the rings) the outer rings would block the light of the star, absorbing all the heat. This would cause that the ring system in the equinoxes would be an outer lava ring and then a normal solidified ring (for small periods of time obviously).
All the idea of cooling and the creation of differentiated temperature on the ring system occurs because I have assumed that the particles are small and thus uncapable of retaining the heat, otherwise the ring would only be a "disk of lava".
I've tried to picture this idea using SE and a few hours at photoshop. Enjoy it
I can't do this better but you get a lot of the idea.
FROM THE EQUATOR OF THE PLANET (NIGHT SIDE):
HERE YOU CAN SEE THE ILLUMINATION (WITH THE OBSCURED EQUATOR) OF THE NIGH SIDE VIEWED FROM SPACE
THIS IS THE RING SYSTEM AS IT WOULD APPEAR ON THE EQUINOXES
AND FINALLY, THE RING SYSTEM AND ILLUMINATION OF THE DIFFERENT PARTS (WITH THE COOLING PHENOMENA IN THE SHADOW OF THE PLANET AND THE HEATING AFTER THE SHADOW). NOTICE THE DIFFERENT SPEED OF THE INNER RINGS WITH RESPECT TO THE OUTER ONES THAT MAKE THE HEATING-COOLING EFFECT ORIENTED IN THAT MANNER.
tHIS HAS TO BE ON SPACE ENGINE (IF ALL WHAT I SAID HAS SENSE). My dream was trully awesome and detailed, I hope to experience it one more time with the future Space Engine
