KOTOR TSL - Help with Replacing hilts (unknown issue)

[SovereignXII 25]

Background: I've learned how to hex edit sabers so I can swap their colours, so now I KOTOR 1 I can, for example. Take OldFlash's Anakin Hilt which replaces Mantle of the Force, and make it replace the Blue hilt AND change its colour to Blue instead of Cyan.

However, I'm attempting to do the same in KOTOR 2, I have OldFlash's TSL hilt replacement pack. It has an Anakin hilt which replaces the Bronze colour. I can edit the blade to make it Blue, BUT. When I rename the files themselves from _007 to _001, the hilt is lacking textures. If I change them back to _007 the texture is back but of course it replaces the Bronze hilt when I'm trying to replace Blue. I haven't encountered this issue in KOTOR1, simply renaming the file makes it replace the corresponding hilt so I'm a little stuck here.

I'll keep trying in the mean time, but any insight into why this is happening would be appreciated. Thank you
