I am adding a new artillery system to the USA and I wanted to add a trailer that follows the projectile. Howevery, after adding the trail, I just noticed that the projectile doesn't travel a very "neat" path. What I want to do is make it so that the trailer has a nice, smooth arch without any sharp turns but I can't seem to get this effect. Any ideas?

It all depends on what settings you're using in the DumbProjectileBehavior module for the shell projectile. Post that here so we can see what you're doing.

Well, I am actually using a MissileAIUpdate, which I think is part of my problem. I want to use the DumbProjectileBehavior but for some reason my projectile doesn't appear when launched and I can't use trails.

well either add this
ProjectileExhaust = (Particle System here) into the weapon code eg.

ProjectileObject = PatriotMissileEMP
ProjectileExhaust = MissileDefenderMissileExhaust;TowMissileExhaust
FireSound = PatriotBatteryWeapon

or add this line ParticleSysBone = None ( Particle System here) in the weapon object code.

eg Draw = W3DModelDraw ModuleTag_01
ConditionState = NONE
Model = AVIonShell
ParticleSysBone = None IonCannonTrailBeam
ParticleSysBone = None IonTankExplosionTrailFlare
End
End

That's a nogo on the second one. It always creates a serious error message and for the first one the projectile still won't show up when using the DumbProjectile setting.

well you must be doing something wrong because it works on mine

Draw = W3DModelDraw ModuleTag_01 
  ConditionState = NONE 
    Model = <name of model>
    ParticleSysBone = None <name of particlesystem>
  End 
End

If it doesn't work, then it is a problem with your code.
