Jetpack colors

[Boba Fett Merc]

Hello guys ! Someone once helped me to make some jetpack mod so the jetpack turns red when your model is /red and blue when your model is /blue but I forgot how he did, I remember compiling things on visual studio but tbh I totally forgot what were the trick, btw I also forgot who did this, I think it was ent (at 95%), but since I've reinstalled windows I lost all the things I had about JKA, furthermore with the same method, it would be fun to adjust the jetpack color to every models, I meant for example, black for shadowtroopers etc... Thx guys !

 

Another question: is it possible to make 2 different .dll working at the same time ?
