Partially Loaded

Fully Loaded

There appears to be an issue with the current version of Blender when thumbnails are loaded too quickly the first time: Try clicking the 'Refresh Libraries' button in the Edit-> Preferences menu, and then clicking a thumbnail but waiting until all the images have loaded.

If you're still having problems,  contact me through my Blender Market page.

The addons works best on meshes containing quad faces - that is, faces with 4 edges each. This doesn't mean your whole mesh has to be made of quads, as you can operate the addon on a sub-selection of faces.  Other mesh topologies may work but are untested.

You can either contact me through the website or contact me through twitter @markkingsnorth.

Try making sure that "Auto-Save Preferences" is checked in the preferences menu, but do get in touch if you have further problems:
