Terraformer.Web

Terraformer.web — Quick 3D Terrain Sculpting Tool

Terraformer.web is a small terrain-sculpting tool inspired by the terraforming mechanics of SimCity 4. Just paint directly on the terrain and watch it rise and fall in real time to shape mountains, hills, rivers, and lakes into a heightmap.

You can also set a water level as a visual reference while you sculpt — note that the water itself is not included in the export.

It's especially handy if you're working with smaller engines that don't ship with a built-in terraforming tool (GDevelop and similar), letting you sculpt your terrain here and bring the result straight into your project.

Note: this tool was originally built for personal use and is shared here as-is for the community. No updates are guaranteed.
