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
