im confused. if you haven't seen my last thread, im trying to make a spaceship. spaceship is more or less done, with animations, but no skin as of yet. before i do skin/(have some1 else do it, i suck at skins) i need to get a stream of particals to come out of back, to look like the burnt off reaction mass, just like the trail a jet leaves behind it. well anyhow ill give u a screeny

looks right right? well apparently its not
Now im not sure if this is a glitch in the previewer or what, but actually even once i get this fixed i got another question... how do i turn it off for certain animations? i mean in its floating "stand" animation, it definalty looks retarted to have a big reaction mass stream behind it, so i need to learn how to control this mofo, and another problem is how do i skin particals/ i still have no idea how to alpha channel anything. HELP!
