Its an editor UMD that lets you choose which parent material instance you would like on your asset, and automatically picks up textures to plug in, assuming you’re importing the mesh to the directory where your textures live, and you have some sort of naming convention.
First time video recording, still working out some recording stuff and deciding a presentation format 
I have some other scripts, like creating a toolbar that auto launches on editor startup, or a button to save versions of a blueprint to a backup folder incase you need to see a previous iteration of an asset. I do a lot of these for work and plan on making more videos.
