Thanks for the support. The ideal way to play my mod, as well as anyone else's incompatible mod, is to copy a vanilla swkotor folder to your desktop as a backup and install my mod into the not-Backup swkotor game. Once you've done that rename the modded swkotor file to anything besides "swkotor" so for example "swkotorngid" for example. After you've done that copy your back up swkotor into your game folder (The location will differ based on the version of kotor you got whether it be Steam, Gog or retail) and install another mod into the swkotor file like K1R. Obviously, you'd repeat the process of copying, installing and renaming and whenever you want to play a mod like the Improvement mod, K1R, Bossr etc you'd rename the folder back to swkotor.
This mod is more complexed than just textures. For example, the replaced low poly background NPC's where done via the appearance.2da replacing the Lite's slots with player appearance's meaning that commoner's on the streets had player heads (I believed he used the Jedi with player heads to replace the Lite models and turned their clothing slot into the commoner clothes so that the head gets swapped for another head if the player head is the same as the commoner's head).
