Projectile editing

[Apache-Cobra]

Hello, how would i go about editing the M136 projectile to not have smoke, and how to edit the tank muzzle flash onto the rear of the M136 to make it more realistic?

I am in the weapons.pbo config now and i have no idea whether i would be scripting the magazine, or the weapon itself.

Please help someone. http://forums.bistudio.com/oldsmileys/notworthy.gif
