Open-source Blender-based 3D editor where AI agents do the grunt work
Intermediate
What is Mixar?
Mixar is an open-source 3D editor built on Blender with AI agents for retopology, UVs, baking, rigging and export prep. It supports bring-your-own models via provider keys, OpenRouter or Codex, and starts with 1,000 free credits.
Mixar is an open-source 3D editor built on top of Blender, with AI agents working inside the scene instead of in a separate app. The agents handle the repetitive parts of a 3D pipeline, including retopology, UV unwrapping, baking, rigging, animation and export preparation, while the artist keeps control of direction. Everything the agents produce stays editable inside the same file, so there is no round trip between a generator and a traditional editor. The tool is aimed at a wide spread of 3D users: solo creators, indie game studios, character artists, technical artists, concept and environment designers, and people working in architecture, interiors, real estate concepting and product visualization. Technical artists can describe UV, retopology and bake jobs in plain language, and character artists can prompt for auto-rigging and posing. Each task gets its own agent, so modeling and texturing can run in parallel rather than one after another. A Zen mode strips the interface down to the viewport and floating AI controls for focused work. In practice, Mixar is downloaded and activated by signing in, and new users receive 1,000 credits to start. Models are not locked in: users can connect a provider key and pay per use, route through a single OpenRouter key that reaches more than 400 models, or reuse an existing Codex subscription to avoid extra API cost. The homepage shows support for model families from vendors such as OpenAI, Anthropic, Gemini, Tripo, Trellis and Tencent Hunyuan, plus video generation inside the editor. The source code is published on GitHub, so it can be cloned, run and modified. Among alternatives, Mixar sits between plain Blender with add-ons and closed text-to-3D generators. Compared with generators that export a single mesh, it keeps the full editing environment and scene file. Compared with vanilla Blender, it adds agentic automation and model choice, at the cost of depending on external model providers and credits for AI work.
