The missile is referenced to missile wake 2 or something similar (away from my home PC at the moment, so unsure of exact name, but you will see it in the .xml file). If you have a look in there it may be obvious. Pete

You are right Pete, the effect is "csweapon_rocket_wake2".
So it would be something that CS would have to modify I guess.
Thanks for the tip.
I will PM you over the weekend, I have another question for you.
