Activity Forums Adobe After Effects Layer Masking in mind

  • Layer Masking in mind

    Posted by Adam Bell on August 24, 2009 at 1:53 am

    I am big photoshop guy, and I am moving into the world of after effects. The following link is what I have done so far. https://www.neweyes.org/sample.mp4

    Basically I have a particle layer doing its light streak effect, I need that to be like at layer mask in photoshop. So it will show a very high-detailed text layer behind its streaks. How do I set this up? I tried track matting and it seemed to be the right direction, but I don’t think I did it right. Any thoughts or ideas?

    From what I can understand, a track matte is indeed what you want.

    A track matte will use the pixels on the layer as transparency for the layer below (using alpha or luminance).
    So if you have the particle streaks and use that as a track matte for something else, the particles will not be shown at ALL but will be a mask through which the other layer shows.

    Not sure what you may be doing “wrong”…

    Well okay, but here is the problem. I don’t want to see the entire layer below until the hand has “particulared” itself over the that part. I photoshopped a frame to show you what it should look like. The bright pink text would be the bottom layer that is “being” revealed while the lightstreak masks its way over it.
