Rational Resources

Rational Resources is inspired by Realistic Atmospheres made by OhioBob and operates on the KSP Community Resource Pack or WBI Classic Stock. Rational Resources strips out the entirely random resource distributions and applies "distribution templates" (carefully configured groups of resource distributions) according to the logically expected class and composition of a body. While this mod is installed, un-configured bodies will have no resources at all except for a little Ore.

This mod enables planet makers to easily assign these distribution templates to their planet packs and skip the headaches of figuring out and writing the individual nodes themselves, and assorting all of their writings into several per-resource config files.

Active Resources

With some partial respect to realism, this mod drastically reduces the presence of the stock "Ore" resource in order to starve the use of this omnipotent and exceedingly abstracted resource, and to encourage the use of the distinct and specialized resources, and to encourage creation and use of the part mods that revolve around these. The exact resources used are named below as a heads-up to players:

Surface and Atmosphere resources * Ammonia, CarbonDioxide, ExoticMinerals, Gypsum, LqdHe3, Hydrates, Hydrogen, MetalOre, MetallicOre, Methane, Minerals, Nitrogen, Ore, Oxygen, RareMetals, Rock, Silicates, Substrate, Uraninite, Water.

Ocean resources * LqdAmmonia, LqdCO2, LqdMethane, LqdNitrogen, LqdOxygen, Water.

Star resources * Antimatter, Karborundum, LqdHe3, Hydrogen, LqdDeuterium.


With omnipotent Ore being stripped of its Godhood, the following ISRU chains are proposed and encouraged for use by seasoned modders. Ore abundance is capped to 5% and its presence chance to 80%. It will be inconvenient for most players... but it will still be around.

Ore tanks will be changed via B9 Part Switch, to hold the cryogenic input resources. The intended ISRU chains that will be provided can be viewed in Issue #1.


Rational Resources purges resource distributions placed by most other mods. Untagged resource distributions are all deleted in the ModuleManager :FOR[zRationalResources] pass. The whitelisting mentioned below largely only applies to global/universal placements, and nearly no specific/per-planet placements in order to prevent unwanted high concentrations like Karbonite on Eve.

Whitelisted resources

  • Antimatter, ArgonGas, LqdHe3, Karborundum, LqdDeuterium, LqdHydrogen, XenonGas. (used by at least the Near Future Tech and Far Future Tech mods).
  • Karbonite, Karborundum.
  • Not Dirt (used only by USI MKS. Its absence should be but a minor hurdle to MKS players).

Easy and full compatibility is granted between a configured planet pack and the following mods:

  • Kerbalism
  • TAC Life Support
  • Near Future Tech suite
  • CryoTanks
  • Kerbal Atomics

Version 1.0.3 for Kerbal Space Program 1.8.1

Released on 2019-11-25

  • Added Restock+ new Ore tanks (KSP 1.8) to Ore tank resource switching.
  • Fixed missing Water in Duna and Laythe polar regions without JNSQ.
  • Fixed specific restrictions at Mun Polar Crater without JNSQ.
  • Fixed missing NEEDS in OPM patch.


Version 1.0.2 for Kerbal Space Program 1.7.3

Released on 2019-10-25

  • Updated SSPXr extras config. Caught redundant/overlapping subtypes.
  • Added WBI logistics module to all stock parts when TankSwitchForSquad patch is active and Rational Resources is in Classic Stock play mode.
  • Tiny adjustments to nuclear engines.


Version 1.0.1 for Kerbal Space Program 1.7.3

Released on 2019-09-23

  • Moved B9 tank definitions to core folder to prevent breakage of established mods containing RR tank type patches when RR parts not installed.


Version 1.0.0 for Kerbal Space Program 1.7.3

Released on 2019-09-18

  • Split all added parts and active stock part modifications (except the experiment and the scanners) into their own mod, RationalResourcesParts. This allows RR itself to be a resource placement mod and absolutely nothing more, for those who want to bundle it or those who just don't want parts.
  • Added nuclear engines:
  • "Panther" clone "Main Coon" nuclear turbojet with built-in nuclear reactor.
  • "NERVA" clones. The "O" edition is high thrust and can choose between Carbon Dioxide and Water. The "R" edition is high Isp and can choose between Hydrogen, Ammonia and Methane. Their mode switch feature requires B9 Part Switch 2.10 or later.
  • Added/Updated LqdHe3 presence via ExoRock, ExoIce, Mun templates.
  • Added LqdHe3 to RR Ground Scanner.
  • Added Water to Duna.
  • Reduced MetalOre tank volume. A full tank weighed far, far too much.
  • WBI Classic Stock:
  • Changed nuclear engines to use Classic Stock resources.
  • Added OmniConverters for cycling Atmosphere and CompressedAtmosphere.
  • Provided tank types. Most of Pathfinder's tank types available to all stock tanks through the Extras config.
  • Fixed small error in OPM science config.
  • Fixed XM-G50 intake patch to use harvester modules for ocean filtering. Intake modules showed very undesired behavior.
  • Changes concerning Eve oceans and Kerosene/LiquidFuel:
  • Added large Ore presence to Eve Shallows biome to compensate for a lack of proper heavy hydrocarbon resource outside of RealFuels.
  • Added Extras: RR_EveLiquidFuelOcean.cfg -- what it says on the tin. Also adds a LiquidFuel harvester module to the XM-G50 air scoop. The idea of this is both very necessary on one hand and very silly on the other hand so it will not be active by default and will not be endorsed for use elsewhere.
  • Removed CRP LqdMethane from Eve oceans as this is cryogenic and should not exist at a hot inner planet. It will still appear at any decent world with hydrocarbon oceans-- cold outer worlds.
  • Classic Stock Hydrokerbon presence is unchanged as it meets the mark.


Version 0.9.1 for Kerbal Space Program 1.7.3

Released on 2019-08-08

  • Added support for the Outer Planets Mod.
  • Added Extras folder with optional configs.
    • Moved stock Ore converters remover here.
    • Added RationalResourcesSquad. This extra applies B9PS and all fuel options to all stock tanks. This also adds non-redundant tank types to CryoTanks if that is installed. (Does not affect CryoTanks if installed alongside WBI Classic Stock.)
    • Added patch for Nertea's SSPXr.
    • Added LqdHe3 tank type which only appears for Galaxies Unbound (a planet pack).
