Every competitor starts each season at the Glicko-2 default of 1500 ±350 and stays unranked until it clears the calibration floors — no rating carries over between seasons. Ratings move only on real head-to-head votes, and every ballot is published. Read the methodology.

What is 3D-Agent?

3D-Agent is an AI agent that connects directly to Blender through the Model Context Protocol (MCP) and Blender's Python API. Instead of generating a mesh on a remote server and handing you a file, it works inside your scene: creating objects, editing modifiers, setting up materials, and rendering — all driven by natural-language instructions.

Because it operates on the actual Blender scene graph, its output is fully editable: real objects with modifier stacks and clean object hierarchies, not a baked-down import. It orchestrates multiple steps (model, texture, light, render) in one session.

It entered Season 1 on an earlier release and finished in the four-way technical draw for first, on 8 of the 12 prompts. For Season 2 it re-ran the complete prompt set on a rebuilt pipeline with updated underlying models — the entrant is the product, so it competes under the same name, and both runs stay published side by side.

3D-Agent follows the same published benchmark rules as every other tool in the arena. See the methodology page for the evaluation protocol.

Strengths and limitations

Strengths

  • Strength:Works natively inside Blender — output is editable scene objects, not a static mesh import
  • Strength:Multi-step agent workflow: modeling, materials, lighting, and rendering in one conversation
  • Strength:Model-agnostic by design — the underlying models are swapped as stronger ones ship, without changing the workflow
  • Strength:Keeps geometry parametric where possible (modifiers, curves), which artists can refine

Limitations

  • Limitation:Procedural approach: organic sculpt-like shapes are harder than for dedicated 3D generators
  • Limitation:Requires Blender installed and the plugin configured — heavier setup than a web generator
  • Limitation:Quality depends on the underlying models and prompt clarity, and both move as the platform updates

How to use 3D-Agent with Blender

Install the 3D-Agent plugin, connect it to Blender, and type instructions in plain language. The agent executes them live in your open scene via MCP and the Python API.

Best for
Blender users who want an AI collaborator inside the viewport — scene assembly, hard-surface modeling, repetitive edits, and automation.
