I have recently made a geometry group that assembles a wireframe mesh by placing cylinders on the edges of a mesh and spheres on the vertices. For one of these wireframes I wanted to rig it to an armature but I found it impossible to paint weights on a mesh without faces dispite weights being applied only to vertices.

I want to have this done without needing to create new edges and faces.

With geometry nodes applied.

Without geometry nodes applied. (Just edges and vertices)

Problem with creating a face with the current setup (creates unwanted edges which my geometry nodes converts into a cylinder)
