    Hello,
    I don’t know if a post like mine already exists, i did not find one, but my question is
    How do i create the effect by Jason koxvold (from the trapcode site) where he creates a light trail as if being drawn in the air by someone.
    thanks

    Yeah, it has been talked about a few times if you want to do a search. If it’s the one I’m thinking about, there should be a short article on how he did it on the Trapcode site.

    If I remember correctly:

    On set they used LED keylights in their hands to create illuminated tracking points. They tracked these and apllied this data to the emitter in Particular (although for this you can use any of the AE built in particles). Then he set the the dynamics so the particles drift to match the camera movement. Then added glow/colored blur effects on the particles.

    Simply create a particular layer….

    1) set particle life to 4 sec (adjust to suit once done)
    2) Choose glow sphere as part. type, 0 feather, size to 1, uniform direction
    3) Size over life set to diagnol upper left to lower right linear line preset
    4) Opacity over life set to quick lower left to upper mid to lower right pseude-pyramid preset
    5) Set Physics time factor to 2.5 (adjust to suit once done)
    6) ‘Velocity’ AND ‘Velocity Random’ AND ‘Velocity from motion’ set to 0

    NO aux particles.
    All other settings default.
    ALL random settings to 0%

    NOW simply animate emmiter (or track it) and nice flowing line will follow in beautiful fashion…..
