Island & terraces

island size0.78

coast fade width0.00

Radial smoothstep ring from solid interior to open ocean. 0 = hard coast edge (no fade).

shore water strip0.14

Outer coast band forced to surface water (mask ≤ this value).

flat beach shelf0.40

Middle coast band pinned to flat land step 1. Lower = thinner beach border.

total land cliff steps12

Redistributes terrace steps evenly across elevation biomes. Per-biome overrides are in Land biome cliff levels below.

Radial island mask Stepped height (Cores em Degraus) Per-biome elevation blend

Radial mask sinks map edges to ocean; per-biome blend uses macro-grid Whittaker zones with per-land height curves.

Whittaker climate

Land classificationEqual elevation bands

Off = legacy height bands only. On = temperature × moisture (same as game). Stone and snow still override at high elevation.

Tundra and savanna appear only when Whittaker is on.

Temperature bias0.00

Global shift on sampled temperature (cold ← → hot).

Precipitation bias0.00

Global shift on sampled moisture (dry ← → wet).

Voronoi regions

Show Voronoi borders Click map to pick region

Each Voronoi region can use a terraform group — an ordered elevation ladder (e.g. dirty-sand → light-grass → stone → snow). Define ladders in Terraform Groups.

Land biome cliff levels

Each elevation biome gets an equal land-unit band (fair height slice). cliffLevels controls terrace steps inside that band (global steps shown per biome). Climate-only entries (tundra, savanna) inherit steps from height at their tile.
