I'm still mainlining tutorials. I want to make my challenge maps specifically for the challenge at hand, though I am hoping to enter one soon. I made and tiled the crosshatching myself for the last one. I couldn't find anything quite like I wanted at a good enough resolution a bit time consuming for something so simple but our brains love to catch on the details. I should post it for anyone who wants it at some point, but it still needs some touch up in places.
