Talus by Tersa

Talus by Tersa is a diffusion model for game heightmaps that generates 4 km terrains in the browser.

Talus by Tersa is a small diffusion model that draws 4 km heightmaps for games directly in the browser. It is built for game developers who need procedural terrain without cloud processing. The system uses a 23M-parameter network trained on 45,000 maps from a procedural generator featuring layered noise, rivers, and sliding rock. It runs via ONNX Runtime using WebGPU or CPU, and keeps weights and runtime in the browser cache. Users can pick a terrain type, adjust settings, and generate maps in 25 steps. Every map includes a JSON file with size and height range, a 16-bit PNG heightmap, and an OBJ file. Users can export these maps to Unity, Unreal, Godot, or Blender, or run Talus locally with a Python tool.
