It's been years since I've loaded up NWN, so I was wondering what good graphics enhancements are out there for the game that I might not be aware of?

One thing that comes to mind is my favorite Alternate Combat Animations v4.0

Doesn't change the graphics as such, but provides neat new combat moves.
Doesn't effect gameplay either, just the visuals.

The NWNCQ Project is rather nice.

It provides graphical overrides for all of the standard tilesets. It does look much nicer, but I stopped using it due to it causing crashes in ONE area on the PW I frequent (never had any other issues with it).

There are also overrides for various weapons, armors, monster skins, hands, etc available on the vault. Most of them are easy enough to find.

Thanks for the suggestions! I found this post http://social.bioware.com/forum/1/topic/199/index/3275241 which seems to be a great place to start!

I do have a question though, I seem to remember at least about Neverwinter NIghts 2 (which I own via Steam) that you can create directories within the override folder and it would still read the files. Will this work for NWN? I ask simply because I like to keep stuff on my hard drive organized.
