Basically what I've done is go through every piece of armor (incuding clothes and robes) piece by piece, changing them as I went. A lot of what I did was just changing the colors. The developers of NWN may be great programmers, but those people are color-blind! Anyway, all told I changed more than two thirds of the armor. It's important to note, that these changes are visual only, I left the stats and abilities as they were. All the armor files from my earlier "My Preferences" hak are there as well, although I changed Grimgnaw's robe to a different color.
To use use my changes, just put all the files into the override folder of the Neverwinter Nights directory. These files should be compatible with other haks, as long as they don't use the same file names as mine. Anyway I put a lot of work into this, so I hope you enjoy.
(I found out what the problem is with items not changing when a new module is loaded. Items added via the cheat console, or found in the module will be the new ones, but any item sold by an NPC will remain the default item. I don't plan on fixing this, as I would have to change every merchant in the game, and I don't have that kind of time. Sorry for the inconvieniance.)
