Hey Ethan,
Great Video! Thanks for the multi-example demo, sooooo much better than one long video about 1 scene for a beginner like me.
I also saw a recent video on using Node Wrangler quick add shortcut Ctrl+Shft+T when highlighting the Principled BSDF and it lets you select all the files you want to link in and it does most of that basic setup work for you and it is super slick. The shortcut works on other nodes too but this has to be the most impressive.
