Why we like it

Blender-Hopper earns its place in the superhive library as a dedicated bridge between Blender's modeling and Grasshopper's parametric tools, moving objects, mesh data, vertex groups and attributes in both directions.

What is Blender-Hopper?

Blender-Hopper, developed by Arthur Vilarinho, connects the Blender software with the Grasshopper plugin to open new workflow possibilities between 3D modeling and parametrization. It can read, write and edit objects, object data, location, rotation and scale, plus mesh data including vertices, edges and faces.

Beyond geometry, it handles vertex, edge and face neighbors, vertex groups and attributes. Geometry control lets you add multiple geometries through rules, and information control covers vertex-groups and attributes. It can also combine with Blender addons and with Grasshopper plugins for climatic, structural and physics simulation.

Setup runs in two parts: import the .zip file locally in Blender, then drag the contents of the .ghuser folder into the Grasshopper viewport. Recommended workflows move data both ways, from Blender to Grasshopper and from Grasshopper to Blender. It uses the GPL license and lists compatibility with Blender 4.5, with Cycles and Eevee as the render engines. A demo video is available.

Who is Blender-Hopper best for?

Blender-Hopper is best for blender and Grasshopper users who want to move geometry, mesh data and attributes between the two for parametric modeling workflows.

How much does Blender-Hopper cost?

Blender-Hopper is completely free to download and use.

Frequently asked questions

Does Blender-Hopper work with Blender 4.5?

Blender-Hopper lists compatibility with Blender 4.5 and is marked as Blender Extension compatible. It's an add-on type extension, with Cycles and Eevee noted as the render engines used. Installation happens in two stages: you import the .zip file locally in Blender, then drag all the contents of the .ghuser folder into the Grasshopper viewport. For versions outside 4.5, check the developer's page at tuca.arq.br for current details before you install.

How do I install Blender-Hopper?

Blender-Hopper installs across both applications. In Blender, import the .zip file locally, and in Grasshopper, drag all the contents of the .ghuser folder into the viewport. One workflow note applies when moving data: apply the geometry nodes modifier before exporting. All data stays correctly ordered, though the cluster for viewing meshes takes vertices out of order, which is resolved during that step. If you only need to modify or create data without visualizing the mesh, you can skip that part.

What data can Blender-Hopper move between Blender and Grasshopper?

Blender-Hopper can read, write and edit objects, object data, location, rotation and scale, plus mesh data such as vertices, edges and faces. It also covers vertex, edge and face neighbors, vertex groups and attributes. Recommended workflows go both directions: from Blender to Grasshopper, exporting the attributes generated in Blender, and from Grasshopper to Blender, creating a new attribute based on the Z-axis position of vertices and exporting it back.

Is Blender-Hopper free, and what license does it use?

Blender-Hopper is listed as free here and is distributed under the GPL license. Licensing terms can change, so check the developer's page at tuca.arq.br for the current situation before relying on it. The add-on was published by Arthur Vilarinho, who also shares contact channels on Instagram and YouTube. A demo video is available if you want to see more before setting it up.
