Install
Manual install
npx @deepseek-ai/dsh plugin --profile web add dsh-blenderInstalls the plugin from npm into the `web` profile. Then run `dsh-blender-setup` for the analysis scripts.

What it does
dsh-blender gives DeepSeek Harness a full Blender-backed 3D workflow. The plugin registers one orchestrator skill, `create-3d-model`, 29 domain skills, 26 analysis helper scripts and 13 tools scoped to the session workspace. Every operation launches a local background Blender process, so no add-on and no open control port are needed. The tools follow the work stages. `blender_scene_info` and `blender_object_info` read the scene, materials, UVs and animation. `blender_import` turns exchange formats into versioned `.blend` files. `blender_python` runs a short `bpy` or `bmesh` chunk and saves a new version. `blender_preview`, `blender_render` and `blender_render_frames` produce images for review. `blender_export` writes GLB, glTF, FBX, OBJ, STL, USD and PLY, while `blender_validate_scene` and `blender_validate_export` audit the result and re-import the export in a clean process. The helper scripts build references, wireframes, contours, multiview shots, UVs, textures and animation checks. For them, `dsh-blender-setup` creates a Python virtual environment in the plugin folder with OpenCV, NumPy, Pillow and SciPy.
Who it is for. 3D artists and game developers who model in DeepSeek Harness and want the agent to take over routine steps: blockout, materials, lighting, validation and export.
Good fit when
- A model has to be built from a reference image and exported to GLB for an engine
- A scene arrived as FBX or OBJ, and you need to import it, check sizes and UVs and export it again
- An animation needs a contact-sheet check before handoff
- A model has to be rendered at draft and final quality for approval
- A finished export should be verified by re-importing it in a clean process
Not a fit when
- You work in Claude Code or Cursor: the plugin targets DeepSeek Harness, and only the skill set works as plain text elsewhere
- Blender 4.3 or newer is not available on `PATH`
- You need an interactive editor with a live Blender window: every operation runs in a background process
Example request
Use create-3d-model: build a desk lamp from the reference, check the UVs and export to GLB.Limitations
It needs DeepSeek Harness 0.2.0-rc.2, 0.2.1-alpha.1 or 0.2.1-alpha.2, Node.js 22.12 or newer and Blender 4.3 or newer. Python 3.10 is needed for the analysis helper scripts. The author verified compatibility on macOS, while rollback and other platforms are unverified, and the plugin has no DSH store approval. The `blender_python` tool runs code with Blender permissions, so enable it only for trusted chunks. `enablePython: false` turns it off, and `restrictToWorkspace: true` keeps input and output inside the session workspace.
How to disable. Remove the plugin with `dsh plugin` for your profile. The `.venv` environment sits inside the plugin folder and goes with it. To turn off the riskiest tool, set `enablePython: false` in the plugin settings.
FAQ
Do I need a Blender add-on?
No. Every operation launches a separate background Blender process, and neither an add-on nor a control port is required.
Which formats can it export?
GLB, glTF, FBX, OBJ, STL, USD and PLY through `blender_export`. After export, `blender_validate_export` re-imports the file.
What does dsh-blender-setup do?
It creates a `.venv` in the plugin folder and installs OpenCV, NumPy, Pillow and SciPy for the analysis scripts. The other tools work without it.
Can Python execution be restricted?
Yes. `enablePython: false` turns off `blender_python`, and inspection, rendering and export stay available.
Where do I open the interface after install?
Run `npx @deepseek-ai/dsh web` and open `http://127.0.0.1:3080`. Create a session whose workspace is the modeling folder and ask it to use create-3d-model.
