    Hi,

    I’m trying to use the Stroke effect to reveal parts of a layer. I am using multiple masks and have a Stroke Effect for each of them (14 masks and 14 stroke effects). I’ve also set each Stroke effect to “Reveal Original Image”.

    For some reason the effect will work on one mask at a time. If I turn off Stroke Effects 2-14 than #1 will work. If more than one or all of them on, it won’t.

    Anyone have any ideas on how to do this?

    Thanks!

    Sorry to answer your question with an indirect answer, but could you not just use a single stroke effect and set it to work on ALL masks? That way you won’t need an instance of the stroke effect for every path. You could then re-order the masks on the layer so that they are stroked in the correct order.

    Hey Simon,

    Thanks for the quick response. I did try using just one Stroke Effect with the “All Masks” clicked but my problem with that is that It seemed like there was no way to control the timing. I’d like for some masks to be revealed at the same time and the others to be a bit more random. It seemed like the “All Masks” goes one at a time based on the order of the masks. Is there a way to correct this?

    Thanks again!

    Not really sure if I understand problem, it never happened to me…
    But it looks like you gonna need 14 layers (each one with its own mask and Stroke effect). Change blending mode for all of them (except bottom one) to appropriate in your situation (usually multiply) to blend all parts together into one gradually revealing image…
    If I’m wrong and we are talking about different things, then I’m sorry. But hope it will help.
    Viacheslav.

    Thanks Viacheslav,

    I actually ended up going with a combination of your suggestion and Simon’s because I wanted some of the areas to reveal at the same time and others to reveal at different times. I just made a few different layers of my image and used one stroke effect on each layer and set it to “All Masks”. This way I could control the timing by staggering the keyframes on separate layers.

    I still haven’t figured out why you can’t use more than one stroke effect set to “Reveal Original” on the same layer but separating the image into multiple layers didn’t prove to be too tough of a task.

    Thanks guys!!

    Put all your strokes effects and masks in a solid layer above.

    Switch all paint styles in the stroke effect to “on original image” except the first – it should be “on transparent”.

    Then just set the solid layer to an alpha tracking matte of Your original layer.

    Now You can control every stroke effect for every mask separately.

    (Btw. sometimes You can change the single mask timing with one stroke effect for all masks with the simple length of the masks… but that’s a bit dirty with possible problems.)
