Wiring Blender through MCP shifts the bottleneck from UI skills to intent

The author says wiring Blender through MCP moved the bottleneck from learning the UI to knowing what they actually want to make.
Main points:
- Blender is exposed as tools via MCP, the same protocol used by coding agents to control external software.
- A capable LLM can then turn plain-language scene requests into Blender actions.
- The author used GPT-5.6 Sol, and says Opus 4.8 also works well.
- In a test scene, they built a tatami room with shoji screens, a low table, a small fan, and afternoon lighting, then iterated by asking for changes like a lower camera, warmer light, and thinner greenery outside the window.
The broader argument is that Blender’s skill moat used to be interface fluency, but that moat shrinks once intent maps directly to tool calls. The bottleneck shifts to deciding what you want, similar to what happened in coding.
The author is especially interested in 3D as a controllable base layer for AI video: direct a Blender scene precisely, render it, then feed it into a video model for more control than pure text-to-video prompting.
