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.
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
