Have been working on extending the Sol system for a few years now to include a number of major asteroids, dwarf planets and a few other stations. Earth has also been fleshed out with 92 surface ports, this number may be reduced if there are still lag issues.
The file will be made available when I fix a rotation_period error that is causing the game to crash when jumping into Sol.
It's not crashing anymore, I ended up trimming down the number of spaceports on Earth. There is still quite a lot of lag, I noticed it's quite smooth though until all the traffic starts jumping in, gotta say the shear amount of activity looks cool, I'll see if I can get a screenshot of it. The engine will probably need improved optimizations, I have 32GBs of RAM and running on a 3GB/s SSD chip so I'm good on processing power. Also added some new asteroids:
1607 Mavis
1550 Tito
1429 Pemba
3628 Boznemcova
Additions include:
Asteroids:
Pallas
Vesta
Hygiea
1866 Sisyphus
2212 Hephaistos
Tyche
Tycho Brahe (with a complimentary Tycho Station)
Psyche
3200 Pheathon
1999 JM8
Chiron
Nessus
Anubis
Saturn: Janus, Hyperion & Ymir
Dwarf Planets
Chariklo
1995 SN55
Salacia & Actaea
Orcus & Vanth
Makemake & Mk2
Quaoar & Weywot
2002 MS4
Sedna
Eris & Dysnomia
Gonggong & Xiangliu
Haumea, Hi'aka & Namaka
Farfarout
New Spaceports:
Helios Station, inbetween Mercury and the sun,
populated Mercury, with two orbitals, Ikarus Rest and Daedalus PitStop
Venusia habitat, ring station orbiting Venus
Gateway, a station roughly between Earth and Luna orbit
Armstrong station, orbiting Luna
Fortuna station, a transit station built between Earth and Mars
Proserpina Station orbiting Ceres along with Ocator Domes on the surface
A populated belt, including Eros, Hygiea, Pallas among others
Future additions include:
-Some more of the asteroids orbiting the gas giants
-Transit stations between: Earth & Venus, Venus & Mercury, Mars & Ceres, Ceres & Jupiter, Jupiter & Saturn, Saturn & Neptune, Uranus & Neptune, Neptune & Pluto.
-Engine optimizations and improvements to make high population systems playable
Forgot to add Gateway station, amended. Also added in the ISS on its same orbital parameters. Some of the orbital parameters of other Earth stations have also been tweaked.
Personally, I don't want to add more stuff to Sol, in the game, but we do need as many custom systems as possible. Ones that don't have the usual "Smith's Orbital" or "Baker's world" name scheme.
I agree, this is quite cool, but I agree with impaktor about the wariness to add any more detail to Sol, if this is intended for master. It would stick out quite much, and pale all other systems in comparison, even the hand-made ones.
I noticed that the Mars BBS on start has quite a lot of entries. Which isn't really a problem in itself, quite the contrary. But it might make the BBS-es of other systems feel quite empty, even if the population is the close.
And this might be a bit much from the UX point of view as well: I had a hard time picking out Earth on the orbit map, because there's no real distinction between any of the planets, dwarf planets and such. This mod would really benefit from a bit of color coding there (different opacity of orbit for each planet type for example), and/or a filter function.
I noticed that some bases seem to be on the wrong body: on Gongong for example, there's a Gongong Base and a Xiangliu Base as well, the later not residing on the Xiangliu moon that orbits Gongong. I saw at least one other example of that misplacement, but I can't recall which one was it.
I got a crash after starting out to one of the outter dwarfs, but I don't know if the system caused that.
And a sidenote: if you package it by mimicking the structure of pioneer/data directory, the archive can just be put in Documents (or ~)/Pioneer/mods and it will be loaded. Name it the same as the system.lua in data, and it will override it. Easier to install and try out I think.
Yeah I agree it's hard to pick out the primary planets as well with so many orbital bodies, opportunity to add in UI filters and options like in Space Engine. Will double check the moons and stations on the dwarfs. I've noticed some of my additional cities on Earth are spawning in the wrong locations despite being given the right coordinates. Also the addition of new bodies and stations can sometimes create a visual bug where a ring generates around Earth and the Moon turns pinky red, something similar happened when I created a custom system for Coruscant.
FYI my recommended tools for making custom systems:
>Space Engine, everyone is going to know this one.
>Universe Sandbox, for playing with system evolution
>AstroSynthesis3, a cheap piece of software by NBOS that can generate an entire sector of random, populated systems.
