Mesh Attribute Utils adds attribute-focused commands to Blender's mesh editor. Mesh > Show Attributes displays the values of the currently selected vertex, edge or face attribute as text in the 3D view, capped at 100 values to avoid crashing with large meshes. Mesh > Batch Set Attributes extends the standard Set Attribute command so you can set multiple mesh attributes for the selection at once, rather than only the current one.
Version 0.2.0 brings two commands to object mode. Object > Rename Attribute renames an attribute on the selected meshes while preserving its data, and Object > Edit Mesh Attribute Schema copies attribute definitions from or to all selected meshes, or bulk-deletes attributes across them.
The developer notes the add-on is useful when working with meshes that carry many custom attributes as inputs for geometry nodes. It runs on Blender 4.5.3 LTS and newer, requires no special permissions, and is released under the GNU General Public License v3.0 or later.
