What is Talus?
Talus is a small in-browser diffusion model that generates 4 km game terrain heightmaps from noise. It targets game developers, letting them export maps as 16-bit PNG, Unity RAW, or OBJ for Unity, Unreal, Godot, and Blender.

Talus pros
- Runs fully in the browser via ONNX Runtime on WebGPU; maps never leave the device
- Deterministic: same seed and settings reproduce the same map
- Exports to Unity RAW, 16-bit PNG, and OBJ, with guidance for Unity, Unreal, Godot, and Blender
- Python tool and open-source repo available for generating hundreds of maps locally
Talus cons
- Fine detail is off — too smooth on mountains, too grainy on plains (spectrum score 11.0)
- Realism score of 66.2 vs procedural ground truth
- First run downloads about 54 MB of weights
Frequently asked questions about Talus
Does Talus work offline?
After the first run, weights and runtime stay in the browser cache, and generated maps never leave your device.
How do I import a Talus map into Unity?
Use Terrain > Import Raw with 65 x 65, 16-bit, Windows byte order, set terrain 4,032 m wide and 1,200 m high.
Can I generate many maps in bulk?
Yes, clone the GitHub repo and run the Python CLI tool (nullscape) with a checkpoint to sample many maps locally.
