@N-DReW25 and @ebmar: It's been more than a year since I worked on this so take this next part with a grain of salt as I'm working with "old-man-memory" here. From what I recall, the same texture is present in both games as I believe I went through KOTOR Tool looking for it. However, I can't recall exactly where the texture is actually used. Your best bet is probably to check the areas where Czerka is located: the Tatooine Czerka Office, Kashyyyk Edean field office, and/or possibly on Korriban (possibly including the areas added by Brotherhood of Shadows: Solomon's Revenge? I would check this myself but I'm at work. If you'd like to look for them, I would start there. (Feel free to post some shots of the sign if you find one or more!)
Update: The presence of Czerka Sign file in both games is confirmed by KOTOR Tool. Doesn't help you find it in KotOR1 but you at least you know I looked for it in the game files (again)!
The animations and other little details are amazing, the dark illumination is nice but for my taste the general result is a little too much dark grey. Anyway is a great work.
It's annoying that there isn't easy directions to install included with the MOD. It has cost to me some time understand how install correctly, moreover with a third program needed that people, like myself, do not use and do not know how it works, so I had to risk a little bit (btw, the video of the included link is useless, above all if english is not native language).
I think it can still be helpful so I'll describe how I got it (of course, first of all, you have to download and install XnView if you don't have it):
1- Unzip all 9 parts of the downloaded MOD in their own folder.
2- Copy/Paste (or drag and drop) all the unzipped files from folder 1 and 2 to your KotOR\Override folder.
3- (for simplify) put together all the unzipped files of the folders 3 to 9 in a same folder (obviously, neither folder 1 nor folder 2).
4- Start XnView, the leftmost button is the Browser with wich you have to search the folder where you have placed together the unzipped files of folders 3 to 9. Open the folder and you must see ALL the files placed in the main part of the screen. Select ALL the files (dragging the mouse, Caps+End... anyhow ALL must stay selected).
5- Right click with the mouse on the files (be sure ALL the files are selected) and in the options shown choose and click the market with the hot key "Ctrl+U".
6- In the new window that appears you must indicate the path of your own KotOR\Override folder, the correct format of the files (TGA) and choose "Replace".
7- Click "Go" button, wait a little and you're ready.
Enjoy the MOD
