Blender MCP
Six artists waiting two weeks for placeholder models from one person
One person could make 3D models. Six people needed them. His queue was two weeks long.
The studio was making a 3D action RPG and every placeholder went through the one generalist.
So a concept artist who needed a dwarf warrior in heavy plate carrying a two-handed axe waited two weeks to see it in the engine. Environment work waited on geometry. Animation waited on meshes. A second generalist wasn’t in the budget.
Blender MCP is Siddharth Ahuja’s project. It lets an AI assistant drive Blender. I added two things this studio needed.
Mesh search from a description. The text is embedded and matched against CSM.ai’s asset library, and the closest mesh comes into Blender as a starting point. Not a final asset. Something to block a scene out with.
Rigging in one call. A single tool call rigs the mesh, sends it to Mixamo, pulls an animation back and applies it in the scene.
The addon runs a TCP server inside Blender and executes JSON commands against the bpy API. That means the artist keeps talking to it: make the armour more ornate, he’s too tall. Each turn is a material tweak or a bone scale.
Placeholders went from a two-week wait to twenty minutes, made by the artist who wanted them. The generalist went back to the models that ship.
