Turn a heightmap into a 3D terrain

Make terrain meshes for games, maps and 3D printing from any grayscale image — bright pixels become peaks, dark ones valleys.

How it works

Where do I get heightmaps?+

Export them from World Machine, Gaea or a map service, or paint one in any image editor.

Which resolution should I use?+

256 is a good default; 512 gives more detail but four times more triangles.

Can I 3D-print it?+

Yes — enable “Solid base” to close the mesh, then download STL.

Procedural game-ready trees with LODs, wind and collision — in the browser.

180+ trees, plants and rocks with LOD0–LOD3 for Unity, Unreal and Godot.

Open GLB, FBX, OBJ, STL and 20 more formats; LODs, variants, stats.

Convert FBX, OBJ, STL, GLB, DAE, 3MF, USDZ and more to GLB, glTF, OBJ, STL, PLY or USDZ.

Shrink GLB files: Meshopt geometry, WebP or KTX2 (Basis) textures.

Reduce triangle count of any model while keeping its shape.

Generate LOD0–LOD4 from one model, named for Unity and Unreal.

Fix units, Z-up/Y-up and the pivot of a model before import.

FoliMesh generates vegetation and rocks with LOD0–LOD3, collision and a pivot at the base — GLB, FBX or OBJ for any engine.
