3D-Agent

3D-Agent is a paid AI agent for Blender 4.2+ on macOS and Windows. It turns text prompts into models, textures, animation and Python scripts inside the open scene, with quad-focused topology and exports to OBJ, FBX, GLB and USDZ.

3D-Agent is an AI agent that runs alongside Blender and works directly on the scene an artist already has open. It ships as a desktop app for macOS and Windows and requires Blender 4.2 or later. Instead of producing a mesh on a remote server and handing back a file, it models, edits, textures, animates and writes Blender Python inside the live scene, then checks its own output in the viewport. It installs its own Blender extension, so there is no manual add-on setup and no personal API key to manage. The workflow is built around plain-language prompts. A user describes an object, such as a fantasy church, a modern house or a plush toy, and the agent builds it in Blender. Follow-up messages build on the existing geometry, so changes like moving a bed, adjusting a light or switching a camera angle can be requested in text, with undo available. A dedicated topology function takes an imported AI-generated mesh and rebuilds it with cleaner quads, fewer vertices or repaired non-manifold edges. Animation prompts cover keyframes, walk cycles, rigs and camera flythroughs, and a scripting mode previews the Python before running it. Exports go to OBJ, FBX, GLB and USDZ, plus any native Blender exporter. The audience is Blender users who want faster blockout and iteration: game developers preparing assets for Unity, Unreal or Godot, architectural and interior visualizers, freelance 3D artists and students. The site also publishes guides on Blender MCP, Claude MCP and Roblox model creation. Among alternatives, the main contrast is with general chatbots that only write scripts they cannot test, and with command-helper plugins that do not generate geometry. 3D-Agent is paid only, with three subscription tiers that differ in monthly prompt allowance, speed, reasoning depth and the number of sub-agents, and every tier carries a commercial licence. Anyone without Blender, or who wants a free tier, will need to look elsewhere.
