Neotex
Neotex is a Blender 2.8 addon that allows you to mass texture objects in your scene, automating the entire workflow from importing objects to saving and naming your final texture maps.
It also allows you to do things in batches such as texture catalogs and material generation.
Along with the addon you also get a 20gb 4k material library.
