Terracraft | Premium Procedural Terrain Generator for Unity

Engine Architecture

Fractal Heights & Valley Flatness

Create organic mountain ranges using seed-based multi-layered Perlin noise (fBM). Adjust the **Valley Flatness** power curve to instantly squash lower elevations into playable plains, and apply **Smoothing Passes** to soften jagged cliffs.

Multi-Climatic Biome Blending

Define unlimited biomes using custom temperature, moisture, and height parameters. Ground textures are blended dynamically using organic wave noise, creating smooth transitions from sandy beaches to snow-capped peaks.

Procedural Roads & POI Spawner

Our generator automatically scans the terrain for flat lands to spawn Bandit Camps or villages. It then triggers a procedural pathfinder to connect these camps with clean, winding gravel roads, carving the splatmap automatically.

Foliage Spawning with Avoidance

Scatter thousands of low-poly trees, rocks, and grass props instantly. The smart spawner randomizes scale and rotation for natural variety, and automatically **avoids spawning objects on roads, water, or steep cliffs**.

Interactive 2D Preview Map

Stop wasting time waiting for 3D bakes. Adjust your seed, temperature, and moisture scales, and generate a 2D top-down climatic preview map directly inside your custom editor window before building the world.
