JDog 11 Posted August 25, 2011 I'm setting up the steam effect for the Nimitz but unfortunately the "velocity vector" argument is in world space. I have the nimitz set as the "object" for the last argument but I don't think that does anything regarding the particles' movement direction. Obviously I want the particles to travel aft of the ship... but right now they travel south of the world no matter the orientation of the ship. Is this possible in the arguments of the array somehow? If not I'm probably going to have to try and come up with some overly complicated way of getting the direction of the ship and converting it into lateral and longitudinal values... gross. ---------- Post added at 11:24 PM ---------- Previous post was at 10:47 PM ---------- nevermind... i had the last arguments in quotes as a string. the example i was going off had it as a string >.> sorry Share this post Link to post Share on other sites
