The shape that works
Survival terrain needs: distinct resource zones (forest = wood, mountains = stone, coast =
fish), at least one danger biome (lava, deep water, frozen waste), and natural shelter
spots — caves, ledges, choke points.
- Resource biomes that map to your craft tree (wood, stone, food, rare materials).
- One persistent danger biome — players' minimap dread.
- Water for fishing & cooling.
- Caves and ledges for shelter and PvP cover.
- Multiple seeds per biome family — rotate weekly.

Common questions
Can I generate multiple maps from the same prompt?
Yes. Generation is seeded — same prompt + new seed = different map with the same vibe. Perfect for season rotation.
Are caves included in the terrain output?
Surface caves and overhangs, yes. Deep cave networks are best authored as parts placed against the terrain.
