Here's something odd for you. I spent all afternoon teaching myself how to create a meteor with particle dynamics. Two emitters Two particles (with shapes) attached to each of the emitters Both emitters attached to a NURBS spehere moving along a curve Even when I start from scratch, I get this glitch. Right in the middle of its path, the meteor's tail detaches for a frame or two at various stages of the animation. Is this a major Mac glitch? Anybody seen this before? .jpg attached. --BBE
