I saw someone started to do an Anathema one a bit ago.. but I haven't seen any progress on it yet, so I decided to do one today. I hope I finall got the .dds file settings that you asked for this time. (there were two DXT1 options: DXT1 and DXT1(alpha), I picked the first one, with 1 bit alpha selected elsewhere in the window). I'll get th POI's up after this gets uploaded.
Final Zonerect settings:
-315, -258, 322, 273
(my next pet project will be to figure out how to do Najena's Tower, since it has multiple levels. you just need a height cutoff to transition between the levels, right? There's a huge spiral staircase that connects all the levels, so I figure I can cut that halfway between each level)
