Mixar ✓

Mixar is an open-source, AI-native 3D editor built on the Blender platform. Its built-in agent, Mixie, takes over the slow parts of a 3D pipeline: retopology, UV unwrapping, texture baking and export prep. Tasks run in the background, so the viewport never freezes while work is being done.

Every object can be handed to its own sub-agent for modeling or texturing. Sub-agents run in parallel and return each result into the same Blender scene, so a full environment comes together at once instead of object by object.

Each stage of the job gets a purpose-built workspace: stencil painting in the texturing room, live island packing in the UV room, retopology overlays in the modelling room. Layer-based texturing stacks PBR effects with masks, blend modes and procedural inputs, and any layer Mixie paints stays fully hand-editable. An in-canvas moodboard generates references, pins style anchors and prompts scene changes without leaving the editor.

Mixar runs locally and the codebase is open, so anyone can inspect it, run it and build on it. Connect your own provider API key, a single OpenRouter key with 400+ models, or an existing Codex subscription, and billing stays under your control.

It is used by indie game studios, technical artists, character and environment artists and solo creators, plus teams working on architecture and interiors, events and exhibitions, warehouse layouts and real estate concepting.
