Atelier2 Engine
Atelier2 is our latest in-house 3D generation engine — the technology powering every Suzanne model.
Atelier2 is our latest in-house 3D generation engine. It turns text prompts and photos into clean, textured 3D meshes, and it powers every model the Suzanne API exposes. You never call Atelier2 directly — you call a stable, named model and Atelier2 does the work behind it. When the engine is upgraded, your code keeps working: the model names and request contract stay the same.
The models it powers
All three public models run on Atelier2:
| Model | What it's for | Inputs | Output formats |
|---|---|---|---|
sculptor | Game-ready meshes, fast iteration | text prompt, 1 photo, or 2–4 photos | glb, obj, stl, fbx |
atelier | Premium fidelity with PBR + detailed textures | text prompt or 1 photo | glb, fbx |
capture | Multi-view reconstruction from a full four-view photo set | 4 photos (front / back / left / right) | glb, obj, fbx |
See Models for the full behavior of each, and Generation Parameters for the tunable knobs.
Polygon budget: the face menu
Atelier2 generates meshes at one of a fixed set of polygon counts. params.faces is a discrete menu:
200000500000(default)10000002000000
Values that don't apply to a given path are clamped to the closest supported value; the actual value used appears on the job row.
Quad topology
Set params.quad to true to produce a quad-topology mesh instead of the default triangulated one. Quad meshes are ideal for retopology and for editing in DCC tools. They are capped at 150000 faces and are delivered as FBX (rather than the usual GLB default).
Textures
Atelier2 generates PBR textures (base color + metallic-roughness + normal) by default. Two knobs control texturing:
params.pbr(bool, defaulttrue) — generate PBR maps. Disable for flat-shaded output.params.texture_quality("standard"or"detailed") —atelierdefaults to"detailed"; the other models default to"standard".
Output formats
Request any subset of ["glb", "obj", "stl", "fbx"] via outputs. GLB is the default and is always produced, except quad jobs, which are delivered as native FBX. OBJ and STL are converted server-side from the GLB. Download whichever format you need once the job is done — see Download a model.
