OK, peepses, here is the steam effect for Javier's carriers. It works in exactly the same fashion as the steam effect for the default carrier (i.e. the effect triggers when you launch from the cat, and basically keeps going).
Just drop the attached file into your main Effects folder, and that's all that's required!
Please remember to to take a backup copy of the original file before you replace it.
(N.B. if any of you are using the "fx_catapult.fx" effect file for Javier's carriers that I posted on Voodoo's Hangar, please rename that, or delete it. You won't need it anymore, but Javier has left that attachpoint in his models so it will look weird if you continue to try and use it!)
@Intrepid,
Yo Randy, your idea is good, but that's what Javier himself tried to do with his original effect, and for some reason, if the effect is allowed to expire, it just don't seem to trigger again!
