Terrain recipe

Starter recipeLoads an editable draft. Undo restores the previous recipe.

Terrain Evolution

Parent for next generation: Rolling meadow

Generate variations and adopt one to keep editing. In Terrain Lab, rename it in Recipe and Save. World Builder saves it with your world. Undo restores your previous draft.

Mutation strength

Keep unchangedLandformMaterialsWaterLighting / AtmosphereVegetation

Advanced mutation seed

Mutation seedThe same parent, settings and seed reproduce the same variations.

Advanced Evolution groups

Materials lock covers source-recipe material weights and band softness, including regional palettes. Landform covers active source noise. Water, lighting and vegetation keep their existing locks.

Palette colors, roughness/metalness, detail strength, region strength and region blend width are editable ordinary parameters. Automated mutation of those groups is deferred; generation preserves them.

Create random recipe / Chaos

Generate a starting landscape, then tune its layers in Shape. Undo restores your previous terrain.

Creation modeTwo recipe regions

Repeat a seed

Seed

Regions

Blend two editable terrain recipes across a soft coordinate mask. Your current sculpt edits and materials stay on the parent terrain.

Recipe internals / Formulas

Seed: meadow-27. Noise reference math, editable material-weight formulas and editable region masks use the existing field language. No JavaScript or shader code executes from these editors.

Surface / Materials

Surface layers

This recipe uses legacy palette bands. Upgrade explicitly to blend color, roughness and metalness without changing height. Ground materials copy those three properties; transparency and creature-skin effects are not carried over.

Water

Water extentWater levelA pond bounds the water surface; carve its basin separately.

Lighting / Atmosphere

This viewport uses World Environment below. Terrain recipe inspection lighting is used by Terrain Lab and Material Lab; it does not override the world.

Vegetation

Terrain tree densityTerrain tree sizeWorld Builder also has its own tree count and enable switch.
