Mod «ReGrowth: Expanded World Generation (Continued)» for Rimworld (v1.3 - 1.4)

ReGrowth: Expanded World Generation (Continued)

Have you ever wished you could tweak the world you plan on to your liking? Remove certain biomes or roads? Make one biome spawn less or more? Make the world the size you want and not the one pre-selected for you? Have more mountains or only the sea with a few islands? Or save your world as a preset for later colonies? Or share that preset with a friend?

If your answer is yes, then ReGrowth: Expanded World Generation is the mod for you! Unlike all other ReGrowth mods, this one is standalone! You don't need ReGrowth:Core or anything else (other than Harmony). It's made for everyone! Whether you like my mods or not.

Here is an overview over everything you can control with ReGrowth: Expanded World Generation:

  • Global Coverage: Is now a slider! Choose the percentage you want!
  • River Density: Want more or less rivers? Now you can!
  • Mountain Density: For all you hikers! Enjoy an alpine world… or one without any!
  • Sea level: Make the sea rise or fall, whatever you like!
  • Axial Tilt:: Works exactly like in Realistic Planets and is fully compatible with it! Planets with higher axial tilts will have more extreme seasonal temperature shifts.
  • Road Density: Control how many ancient and faction roads there are.
  • Biomes: Control each and every biome you have, from vanilla to modded ones. Finally you can create ANY planet you can think of! From boreal worlds to sea worlds with desert islands or a Mars like hellscape. It's in your hands!
  • Multiplier multiplies the spawn value of the biome by the chosen percent.
  • Offset adds or removes the chosen amount from the spawn value.
    • Both sliders are added to allow more control over biomes. This will take some playing around for you to get the hang of and fully understand. If you just want to disable one, set the multiplier to 0%.
  • Factions: Have not been changed. The game already allows a good amount of options here!
  • Presets: Allows you to save and load presets, similar to how it works in “EdB Prepare Carefully”. Later we will allow modders to ship their own presets with their mods so they can share their version of a planet with you!
  • Planet Preview: That one is something we added because we wanted to see if we can. And we could, but it has its limitations! Like the world you play on, each preview needs to be generated which can take quite a long time depending on whether you have a 30% coverage or a 100% one. So be patient with it! It does however not freeze your game and can be completely ignored. We will see if we can further optimize it in the future.
    • It does however allow you to see how the planet you are making would look with your current setting. It's not 3D, so you can't rotate it.
    • I also want to be clear that this mod has NO training wheels. You can go crazy with it. If you make a sea ice world and set the temps to maximum you get 70 °C ice sheets. You can do whatever you want!

We tried to make it work with as many other mods we could right away, here is a list:

  • Realistic Planets
  • My Little Planet
  • Rimwar
  • Colony Groups
  • Roads of the Rim
  • Any modded biome.

The mod requires: Harmony.

  • Update to game version 1.4
