I think this mod is a really neat addition; it's to K1 what the Crimson Heads were to RE-make years ago. My only problem is that this conflicts with a number of other mods that modifies KotOR's main "appearance.2da" file. A number of later game characters in my game often get replaced with a Rakghoul Fiend. Funny, but immersion breaking.
EDIT: Found the issue was other later mods that hard-write over the appearance.2da file instead of modifying it. So, lesson learned and this mod now runs butter-y smooth with those files uninstalled. Warning to anyone getting mods that don't modify existing appearance.2da files: don't.
