Creating 3D is hard. LLMs seem to be getting better at tool use and spatial understanding. While MCPs have proved to be a good way to use these tools- the current methods have these challenges:

- Access to scene graph and core C modules of Blender

- Lack of parallelism, only way is to run blender headless

- Lack of deterministic and fast verification layer

- Inference stack- only way to use inference is to hook another MCP

We're building Mixar, think Cursor for 3D. One access point to all generative inference, an agent to build scenes/blockouts, do boring stuff like UVs and export standard formats(.glb/gltf/obj/gbx/usd etc.)
