Habitable Main Planets

Current OXZ - Version 1.3.3

Can planet with radius 3000 km or so be advanced agriculture world with population of billions residents? Definitely no any way. Such planet is too small to maintain dense AND warm atmosphere. Located in habitable zone small planet would has extremely rarefied atmosphere with pressure about few millibars or less.
This OXP redefines vanilla planet database to more realistic values.

Habitable Main Planets was developed to adopt PlanetEngine, integrated onto Planetary Systems OXP, to main planets. PlanetEngine calculates atmosphere temperatures and pressures depending of planet mass and insolation level, but some of vanilla main planet population has unrealistically low radii to be densely populated worlds.
PlanetEngine with Habitable Main Planets gives more reliable data for main planets too.

Minimal radii of planets with biomarkers in description such as tree, forests etc are increased to 5200 km.
Minimal radii of agricultural planets with TL > 3 AND without biomarkers are increased to 4250 km.
Minimal radii of Famous Planets without biomarkers are also increased to 4250 km.
Radii of all above listed planet are proportionally scaled using 6400 km radius as reference point.

Unchanged planets:
Radii of all planets above 6400 km.
Industrial planets beyond Famous Planets list AND without biomarkers.
Agricultural planets with TL below 4 AND without biomarkers.

Minimal air pressure on surface level for planets with biomarkers is approx. 0.5 bar, permitting flourishing natural ecosystems and outdoor activity without breathing equipment.
Minimal air pressure on surface level for agricultural planets or Famous Planets without biomarkers is approx. 0.2 bars, permitting outdoor activity without pressurized suits, only with breathing equipment. It seems too harsh environment for advanced agricultural worlds, but aquaponic farms can be solution.
Small agricultural planets with TL < 4 has too low air pressure to permit any outdoor activity without pressurized suits. Due to new legend such planets are mining worlds, but it is a different story.
More info about PlanetEngine will be in the relevant topic.

Dependencies

Habitable Main Planets OXP can be used per se as pure ambience, bit it provides more realistic background for PlanetEngine. So Sun Gear and Planetary System OXPs are recommended.

Known Issues

Unfortunately this readjusting did not completely eliminates conflicts with vanilla descriptions such as "The planet Atrare is cursed by vicious mountain monkeys" (case for poor industrial planet with radius 3144 km). Procedural generation is so procedural :-)
Setting minimal radius to 4250 km or above will partially solve problem, but I prefer to allow more variation in main planet physical conditions. If you plan terraforming missions planet with almost zero atmosphere pressure will be a bit wrong target, isn't it?
Distance between witchpoint and main planet in vanilla game is pseudo-random value in range 10...14 main planet radii. Since Oolite 1.82 this distance is defined as absolute value – parameter planet_distance, so increasing Leesti vanilla radius from 3085 km to 4411 km for example will only slightly affect distance from witchpoint to main station and travel time. Main station is always positioned on distance to main planet surface equal to main planet radius, but some OXPs using absolute coordinates for positioning of additional objects will not function as intended after installing Habitable Main Planets.

In Oolite 1.88 the vast majority of planet data is not procedural. There should be nothing stopping you from overriding the descriptions of planets inside your own planetinfo.plist.

Of course planet data in Oolite are not procedural generated per se. It just replicates procedural generated data of 8-bit Elite planet data for historical reasons.
Overriding of vanilla planet descriptions in Famous Planets was terminated after approx. 100 entries, so vast majority of Oolite planets has descriptions inherited from procedure generated Elite world. This is more correct formulation of problem.
I don't think these vicious mountain monkeys and spotted wolves are bad - this is a part of fun :D

Hi Just thought I would report back a few of my findings after playing this oxp for a while.
I found that whilst I was at Cevege (TL12 Communist state in galaxy 1) that the oxp appeared to have strongly altered the geometry of the map.
Travelling to a Collective Zero Gravity Factory (located right next to the sun) would usually take a considerable journey even using torus drive, with HMP installed it seemed a very short journey (almost like the planet and the sun were almost beside each other). If more info needed see http://wiki.alioth.net/index.php/CZGF

I also found that the Collective Zero Gravity Factory constantly seemed to have traffic stuck in docking queues, it appeared that ships would stop on approach and allow traffic to build up, almost like the ship at the front was confused or unsure. If I was persistent and patient I could move my ship to within 200 - 300 metres behind the stuck ship in order to get it to slowly move forward a short distance, by slowly doing this repeatedly I could eventually get it to dock.
Wish I had taken some screen shots for you to show what I mean.
I must also stress that I only tried using this oxp in 1 or 2 systems (think I also went to Raoror TL9 Anarchy which is 1 jump away from Cevege)

Hope this may be of some help.

Cheers

Habitable Main Planets was planned to use in vast solar systems, generated by Sun Gear and Planetary Systems. Maybe it will be better to declare HMP dependency from Planetary Systems in future update - without Planetary Systems it is just ambience with already mentioned issues.
There are issues with correct positioning of some objects in vast dynamic solar systems. Maybe Rustem will help to fix these issues - he has more adequate skills in this area.
And thank you for feedback once more!

Apologies - I should have pointed out that I am using Planetfall oxp rather than Planertary systems as it is available via the in-game download manager.
Will be Planetary systems oxp be added to the download manager?

Thanks

You have no reasons to apologize, sir! I must apologize for issues with Sun Gear and HMP.
Yes, Planetary Systems will be uploaded later (I hope, this week).
Planetary Systems is not alternative for Planetfall. You can use Planetfall with Planetary Systems and Moons, I hope.

Just realised that I am confusing Planetary Systems with PlanetLand :oops:
Eejit! :lol:

Speaking of which is there a download for PlanetLand available ?

PlanetLand is a bit different story. It is heavy modified PlanetFall with concept "one planet - one port", but with improved market rules (price and quantity of item depends on system TL and economic specialization) and tons of graphics.
Graphics is a main issue. Assembling this OXP personally for me and my friends from Russian Ooniverse, using sci-fi and landscape wallpapers. So part of content may be in "gray" legal zone. :oops:
Maybe it will be better to reassemble PlanetLand in lite version before presentation.
In any case PlanetLand is terminal branch of my personal Ooniverse. It depends on Planetary Systems and System Makeup (not presented yet too), so I'll convert my OXPs step by step - firstly Sun Gear, then Planetary Systems and Moons.
