For all the years (13) NWN1 has been out I would have thought that there would be a youtube tutorial for just about everything for NWN. However I have been searching all over youtube and there really isn't that many tutorial's for NWN. Most of the tutorials on for NWN on YouTube are about scripting. I was trying to find tutorials on making tilesets, working with .set files, and swapping models from one tileset to another.
I was able to find.........
Aurora Toolset (11 video walk though)
Scripting (8 video walk though)
Animate NPC (single video)
Custom Portraits (single video)
NWN Java 3D model Viewer (single video)
GMax (6 video walk though)
GMax Animation (40 video walk through)
