Twelve Biomes, Wrapped Around a World.

Every Cosmic Scale playthrough rolls a unique world, but the building blocks are the same twelve hand-tuned biomes, tiled across the surface of a real sphere you walk. Each one has its own moisture and temperature range, its own mountain rules, its own resource economy. Find iron in the Boreal Forest, quantum crystal in the Crystal Plains, sulfur in the Volcanic Highlands. A planet type is a climate window, so 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 Unity asset.

Reading the cards

PRIMARY
The dominant terrain type of the biome. Shapes the visual palette and what your starting tiles look like.
MOUNTAINS
Each biome carries its own mountain rules, but mountains are on the bench while terrain gets rebuilt for real spherical planets. Read these as where ranges will form once they land.
RESOURCES
Ore, plants, and rare materials that spawn most often here. Some resources are biome-locked.
DANGER
Ambient hazards and density of difficult terrain. Low biomes are safe expansion zones. High biomes are scarce, broken, or under-resourced.

Worldgen

How worlds form.

Each biome is selected by sampling a warped moisture and temperature noise pair. The result is then run through a 12-biome lookup table tuned to feel hand-placed.

Mountains are on the bench while terrain gets rebuilt for real spherical planets, but the design underneath reads like this: a 2-octave Perlin mountain mask picks WHERE ranges form, and a ridge-folded height noise drives the actual elevation inside each mass. Single-cell anomalies are smoothed out so canyons read as deliberate canyons, not noise dots.

Water bodies are flood-filled and size-validated (100 to 750 tiles) so you never get one-tile drops or worlds-spanning oceans.

Generation Pipeline

  1. 01 Sample warped moisture & temperature
  2. 02 Select biome from 12-biome lookup
  3. 03 Sample mountain mask & height noise (paused during the mountain rework)
  4. 04 Smooth single-cell anomalies
  5. 05 Flood-fill water bodies, validate sizes
  6. 06 Apply terrain types, IsMountain, walkability
  7. 07 Spawn resources with biome rules

Each seed is a new planet.

Rare resources in different biomes, water in different places. Every Cosmic Scale playthrough lays out a different factory.
