I'm using GLTF as a common export format, because it's open source. It also appears that gltf files with just a material are actually valid according to the GLTF validator. I'd love to be able to import these materials in blender, without having to add a mesh.

Allowing just material imports would be a nice feature to have.

The only real alternative I see is inventing a custom format, and I REALLY don't want to do that.

I'd implement it myself, but my python skills are next to nonexistent...

Greetings!
