I got to get some info on a problem that has been bugging me. The Curst Swordsman model added in patch 1.69 has an incorrect appearance.2da entry which causes the tattered robe to appear with mirror-like textures instead of holes.
To fix this, download the Full 2DA Source File from the bottom of the
BioWare Miscellaneous Files page. Then unpack appearance.2da to your override directory and open it in a text editor. Go to line #16 (Curst_Swordsman) and change the entry under the ENVMAP column from "default" to "****".
All fixed, now we just need to get the other 4 million NWN owners to do this and the bug will be fixed for everyone!
