How the studio works

Every change re-meshes the terrain live. Drag the viewport to orbit, scroll to zoom.

Octaves & persistence — stack noise detail layers.
Lacunarity & scale — set the frequency of the relief.
Rain droplets — hydraulic erosion carving valleys.
Sea / tree / snow lines — biome bands (instant recolor).
Export PNG — download the heightmap as 8-bit grayscale.
