HOW IT WORKS
1LLMs drive a real Blender through MCP tool calls — no human hands.
2Every run gets standardized renders + the model's own hero shot.
3You vote on blind pairs; Bradley–Terry turns votes into the ranking.
*** COMING SOON ***
Second Wave SOON
TASK SUITE
The current tasks ask: given a blank scene, can a model make something beautiful? The Pipeline suite asks the question every production artist cares about — given someone else's file and a concrete job, can it do real Blender work?
- Retopology — clean quad mesh over a dense sculpt
- UV unwrapping + PBR texturing on an untextured prop
- Rigging — armature, weights, working deformation
- Rig animation — a looping walk cycle on a provided rig
- Scene cleanup — naming, hierarchy, orphan data
3D Bench SOON
SIBLING BENCH
A sibling benchmark for the other ways models make 3D — no Blender required. Same blind-vote format, pointed at code that draws.
- three.js scene generation
- p5.js sketches + generative scenes
- Judged by the same pairwise human voting
BYOK SOON
RUN YOUR OWN
Bring your own key. Point your own API key at a task and run a model through the bench yourself, then drop the result into the arena.
- Your key, your model, your run
- Any task in the library
- Results feed the same leaderboard
