Eleven Biomes, Wrapped Around a World.

Every world in Cosmic Scale has a planet type, and the type sets its climate window: temperate worlds, arid, frozen and volcanic ones, barren rock, airless moons, acidic and crystalline worlds, and the gas and ice giants. The ground inside that window comes from the same eleven biomes, picked off one climate table with how hot it is down one side and how wet it is across the top, kind of like each planet type setting its own thermostat. So your home world sits in the middle and gets grasslands at the equator and snowfields up by the poles, while a frozen world only ever gets the cold end. Find iron in the Deep Highlands, quantum crystal in the Crystal Plains and sulfur in the Volcanic Highlands, and since no single world carries every biome, the mid and late tech tree can't be finished from the home world alone. Click any card for the real spawn tables straight from the game's files.

Reading the cards

PRIMARY
The dominant ground of the biome. It shapes the visual palette and what your starting ground looks like.
MOUNTAINS
Each biome still carries mountain rules in its data, but every planet is a perfectly smooth sphere on purpose, so there are no ranges to find on the ground right now.
RESOURCES
Ore, plants, and rare materials that spawn most often here. Some resources are biome-locked.
CLIMATE
The moisture and temperature window the biome claims. The planet type sets which windows a world can reach.

Eleven biomes orbit the center. Hover to pause the rotation. Click any biome to read its identity in one paragraph. Scroll down for the full data cards.

Pick a biome and the world turns to where it grows, outlining its ground and raising its resource nodes as pins sized by their odds. The planet type buttons take you to the worlds that carry the rest.

Worldgen

How worlds form.

The ground uses the same kind of noise that shapes worlds in Minecraft and No Man's Sky, called Perlin noise, which looks a lot like TV static smoothed out into soft, cloudy shapes, and the game stacks it in layers called octaves, kind of like painting a landscape with big brushstrokes first and then smaller and smaller brushes for the detail. That noise decides the moisture, latitude decides the temperature just like it does here on Earth, and the two together pick each biome off the planet type's slice of the climate table.

Every planet is a perfectly smooth sphere on purpose. The only dips you'll find are the lakes and oceans, and they're not always water.

Seas fill the low basins on the worlds that have them (water on temperate and frozen worlds, acid on acidic ones, magma on volcanic ones), and the ground near the poles rises above the sea.

Generation Pipeline

  1. 01 Sample warped moisture & temperature
  2. 02 Select biome from the planet type's list
  3. 03 Mountain mask & height noise sit unused (every planet is a smooth sphere on purpose)
  4. 04 Smooth single-cell anomalies
  5. 05 Fill the basins below sea level with the world's sea
  6. 06 Classify each 6 m build cell as land, shore or water
  7. 07 Spawn resources with biome rules

Every seed grows a different planet.

Roll a different seed and you might land on your home world and find a giant ocean sitting right where there wasn't one before, with the ore in different places too, so every playthrough lays out a different factory.
