Re: 'Tracer bullets' expression?

Thanks guys, I will check out that tutorial. And thanks Kevin for that tip about the light, I knew I could use a light as a motion path for Particular but I didn't know about the other controls. As it turns out it is proving difficult to use that technique on the piece of test footage that has been given to me, it seems to be difficult to 'aim' the particles so that they looked like they are disappearing into the distance and still follow the natural direction of the plane by using two trackers, nose and tail. In principle it ought to work, and be easy, but I haven't quite nailed it yet.

The shot I have been given has the camera mounted on the side of the plane, looking forward and showing most of one wing. I have simply tracked one point near the nose and stuck the emitter (using 'Directional') to that. I am manually fiddling with the XYZ rotation parameters until it looks right. Can you see any way of using another tracker, further back on the fuselage (to give me a straight line along the plane), somehow taking this information and plugging it into the rotation parameters so that the particles always shoot along the planes axis?

Cheers
