Here is a mod i found searching a bit around at google. The mod updates all standard jk2 model and make them look serval better, it updates the sabers aswell and gives them a cool new effect and finally it updates the textures at ffa_bespin and gives it a really nice new look.
All you simply gotta do is download the file from this link.
[You must be registered and logged in to see this link.]And then you just unzip the folder and copy the two files called.
texturepatch.pk3
and
Update4Texturepatch#1.pk3
into your base folder and then you got a brand new better look for all the standard jk2 models, saber and ffa_bespin.
Enjoy
