Hello houdini guys

I have stupit beginer question. I finally hammer out miguel' s meteor shader. As some years maya user I don't understand 80% conections in this shader, but it works hihi. I fell love in Battlestar Galactica, cool serial and of course cool space trickx. I want do do something like when raptors shot 4 missiles together. They has deformed spiral trajectory, in maya no problem, put emitor on path via path animation, done. In houdini I found in object level(scene level) path object. Add curve but my particle come with ball emiter. This is why miguel has transform node in geometry level. But, is there some node or something, becouse in transform node there is no place for path object, how I could solve this problem? Another question. Ok I have path object connect in geometry level and have one trail, I create another 3 curves in object level and only need copy the same ball emited particles. How is the most elegant way to do it in houdini. I'm so sorry for that stupid question, but houdini really absolutely change anythin which I learn for almost 7 years in max maya, rhinoceros. It is soooooo differend and so confusing for me, but I'must be hard to my self hih . Thank a lot. BC
