I was recently using KT to modify a weapon to be fully upgradeable, and after veiwing the GFF file I did the following:

Label: UpgradeLevel Field - Type: byte Value: 0

I switched the value to 3 so the weapon had 3 open Ports. It worked on my Blaster Rifle so I decided to change one of my Blaster Pistols to 3 also.
But the .UTI file of the Blaster pistol INCREASED size from 4 KB, to 13 KB, I have no idea how it did that since the only thing I tweaked was the upgrade level.

Now the mod doesn't even work in game and I get errors when I try to load the file in the GFF editor all I get is,

Exception of type System.OutOfMemoryException was thrown.


I have no idea what to do! I really need to fix this!

Sounds to me like your UTI file has been corrupted. (Tech-babble: A loop in the GFF tree could cause those load errors). I doubt there is anything you can do to repair the file, you'll likely have to start over with a new copy, unfortunately.

Which GFF Editor are you using?

(The Upgrade field in KotorTool's item template editor isn't working, at least it wasn't last time I checked.)

I was using the GFF editor in the KT, is there another program I can use that wont corrupt the files then?

you could try the Robius GFF editor or the NWN GFF editor, I think there are links in one of the sticky's about mod tools

Or there is tk102's K-GFF program that was designed with the Kotor games in mind as it handles the camera angles field and a few other glitches because of the differences between NWN and Kotor. Tk's utilities can be found at http://www.starwarsknights.com)

I downloaded tk102's version, thanks for the help!

While we have come to the conclusion that your file is corrupted, I thought I should inform you of something else: Do not worry if editing your files in KotOR Tool increases their size. KT includes a number of new fields in your GFF format file to tell the Tool how to operate. These fields are:

Label: KTInfoVersion Field - Type: CExoString Value: 1.0.2210.16738
Label: KTInfoDate Field - Type: CExoString Value: 25 July 2006 11:12:47
Label: KTGameVerIndex Field - Type: int Value: 1

Fred has also been known to add handy tutorials for beginners in the "Comments" field, I believe an example is the waypoint file. This can increase file size quite visibly.
