WORLD GENERATION
Procedural Terrain Generator
Explore seeded noise, scale, and octave settings with a live terrain heightmap preview.
SEEDED VALUE NOISE
Preview terrain settings
Procedural terrain guide
Procedural terrain is a pipeline, not one noise function. Seeded noise is only the start of shaping regions, biomes, rivers, cliffs, and playable routes.
Use the result as a balancing or prototyping starting point, then validate it against your own game data and playtests.
Separate shape from gameplay
Generate a stable height or density field first, then apply masks and gameplay constraints as explicit stages. Keep the seed and parameters versioned so a world can be reproduced after updates.
Worked example: shaping an island
Start with a fixed seed, a broad feature scale, three octaves, 50% persistence, and a 35% sea level. Raise the sea level to compare how much playable land remains, then try several seeds before choosing a setting that supports routes and landmarks consistently.
Assumptions and limits
The preview uses deterministic value noise and does not model erosion, biome logic, streaming, collision, or gameplay reachability. Treat it as a parameter sketch rather than a production terrain generator.
A practical production check
Record the assumptions behind the estimate, test a small and a worst-case scenario, then compare the result with a profiler, playtest, or representative content sample. This turns a one-off number into a repeatable design decision.
Prototype first, tune second
A calculator or generator can expose relationships quickly, but the final values should be checked against player experience, content cadence, and the rest of your economy or combat system.
Frequently asked questions
Does this replace playtesting or profiling?
No. It provides a fast, repeatable baseline so testing starts from informed numbers rather than guesses.
Can I use this for a shipped game?
Yes, as a planning and comparison aid. Confirm critical budgets with measurements from your target hardware, network conditions, or production data.
Does my data leave the browser?
No. These tools run locally in your browser.
Privacy note: terrain previews happen in your browser. Nothing is uploaded.
