I've modified an existing vanilla mesh from Zeta to use as a muzzle flash and it works just fine on machine guns, but it doesn't seem to show up on a custom rocket launcher I've made. I'm not sure the problem is the in the mesh or the GECK. Not only that but I've tried using other muzzle flashes on my rocket launcher and they worked, you could see it, but even though I had the duration set for 5 seconds it'd only last for half a second. Anyone got any clues as to whats the problem?

ok I found out why the muzzle flash wasn't apeearing, but it doesn't make any sense. If Ammo Use is set to 0 the muzzle flash works as intended, but if its set to 1 or higher it doesn't appear when you shoot. This is driving me nuts.
