How do you delete this ? it seems I have to select the mesh in order to delete it , then it deletes the mesh also.or if I select the mesh and unparent, it disappears. if I select it and click “remove joints” it says it cannot remove a root bone.If I open the hypergraph and select and delete the bottom one, then the mesh disappears. It seems the top one is tied to everything so if I select it and delete in the hypergraph , everything disappears.
