Final Product What You'll Be Creating

In this 2 part tutorial we get our hands dirty with a little expression math to create some beautifully organic light streaks that are used to reveal the AETUTS logo. In part 1 Lloyd breaks down the science behind creating a simple expression that drives the light streak emitter and shows you how easy it is to create infinite variations with ease.

    Why do i keep getting ” After Effects Warning: is not an object
    expression disabled

    Error ocurred at line 4
    Comp: “Comp 3″
    Layer: 1 (”Emitter”)
    Property: “Position
    My Expression thingy is set to
    x = Math.sin (Time * 10) * 10
    y = Math.cos (Time * 10) * 10
    z = Time * 10
    [x,y,z] + value

      javascript is case-sensitive so you need to make sure everything is capitalized correctly and in this case time should not be capitlized. You also need to add semi-colons ; at the end of each line:

      x = Math.sin (time * 10) * 10;
      y = Math.cos (time * 10) * 10;
      z = time * 10;
      [x,y,z] + value

      Your expression should be:

      x = Math.sin (Time * 10) * 10;
      y = Math.cos (Time * 10) * 10;
      z = Time * 10;
      [x,y,z] + value

      (simple matter of the ” ; ” )

    hmm my trapcode particular isn’t emitting anything when i apply it. Basically i apply the effect change the type to light and nothing, still just the light operating on the script.

    any ideas??

    Did buy and download, Trapcode Particular or does it come After Effects CS4?

  5. Diamondstar says:

    Awesome TUT AE, brings back trig flashbacks :)

  6. marina says:

    is ther any other way to do it without using a tripcode preset- i dont have it.

  7. looney says:

    hey great tut,
    although it seems that when i go for 32b color, when i set my logo to obscuration layer, particular doesn t really go around this. Its like the same thing to put an obscuration layer or not. Please help, I cant find anyway to solve the issue.

    thanks

  8. looney says:

    ok i got it. It was because of the light, makes the logo too bright…

  9. Michael says:

  10. Michael says:

  11. tiff says:

    hey lloyd your tutorial seems to keep freezing in the middle of the Day one. Is there any problems on your end

  12. Swaid says:

    I can’t seem to find the expression where you put the sin and cos in

    Help?!

  13. Interesting. Been trying to learn a new language for a while now so this is highly relevant! Thank you.
