I'm trying to make a brown key door with this mod: Various Community Keys. It comes with a lockdefs script, but it doesn't show up when I set a lock in UDMF. It only shows the default keys (red, blue, and yellow). So how do I add a thing that says "You need a brown skull to open this door."? Also I'm using Doom Builder 2, with ZDoom in UDMF format. And I'm not using GZDoom builder its too confusing for me.
