Meshma/Blender/TracePen

TracePen for Blender

Install as a Blender 4.2+ add-on. Trace an image and import native Bezier curves directly into the scene — one curve object per colour layer, holes as inner loops, materials assigned automatically. Convert to Mesh with one click for boolean / extrude workflows.

Bundled wasmtime wheel runs the deterministic tracer fully offline. No upload, no account — only network call is the license-key validation against meshma.com.

Blender 4.2 or newer.

Install

1. Download tracepen.zip.
2. In Blender: Edit → Preferences → Get Extensions.
3. Click the ▾ dropdown (top-right) → Install from Disk.
4. Select the .zip file. Add your license key in the TracePen panel.

The TracePen panel appears in the 3D Viewport sidebar (press N) under the TracePen tab.

Workflow

1. In the 3D Viewport sidebar, open the TracePen tab.
2. Click Open Image and pick a PNG or JPG.
3. Adjust Colors (auto-detected on open) and per-layer Noise Filter / Min Area / Corner Smooth.
4. Choose Image type: Logo / Vector preserves the exact palette, Photo / Gradient smooths tonal transitions.
5. Choose Output: Mesh (filled faces) or Curve (editable Bezier curves).
6. Click Vectorize.

Each color becomes its own object inside a TracePen collection, sharing the preview empty's transform so the result lands in place.

Frequently asked

Which Blender versions are supported?

Blender 4.2 and newer. The plugin uses the modern Extensions system; legacy add-on installs (Blender 4.1 and earlier) are not supported — use the online tool with SVG export instead.

Does it send my image anywhere?

No. Once installed, tracing runs locally via an embedded WASM core. No network call, no account required.

Can I edit the result afterwards?

Yes. Mesh output gives real Blender meshes — Edit Mode, modifiers, Solidify, Boolean, everything works. Curve output gives editable Bezier splines for retopology or motion-path use.

Does it use AI?

No. Deterministic tracer — same image in, same geometry out. Reliable for production work.
