3D-Agent
by 3D-AgentAgentPaid plans from $19/mo (no free tier)
Desktop AI agent for Blender (macOS, Windows) that works directly on your open scene through Blender's Python API, building editable objects rather than importing a baked mesh. No MCP setup or API key.
How to use 3D-Agent with Blender
Install the 3D-Agent desktop app (macOS or Windows). It sets up its own Blender extension, so keep Blender 4.2+ open and type instructions in plain language in the app. The agent executes them live in your open scene through Blender's Python API. On the Ultra plan it also runs its own MCP server, so tools like Claude Code or Cursor can hand it Blender tasks.
Best for: Blender users who want an AI collaborator inside the viewport — scene assembly, hard-surface modeling, repetitive edits, and automation.

What is 3D-Agent?
3D-Agent is a desktop AI agent that works directly on your open Blender scene through 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 3D-Agent desktop app — heavier setup than a web generator
- Limitation:Paid plans only, no free tier: Basic $19/mo, Pro $29/mo, Ultra $89/mo
- Limitation:Quality depends on the underlying models and prompt clarity, and both move as the platform updates
