    In particular, the shatter effect, though I doubt its importance.

    I am relatively new to After Effects, and I’m playing around with it in the university labs. If they’re not going to teach me how to use it, might as well teach myself, right?

    Anyway, I am attempting to use the shatter effect, but to no avail. I can get it to work fine, but I don’t want it to start at the moment that object appears on the screen. I want it to start a certain time after that. I don’t seem to find any setting as to when to start it, and keyframing its strength from zero to whatever over the period of one frame does not do anything.

    I’m probably missing something obvious, but maybe not. Any help would be appreciated. Thanks.

    You might try splitting your layer (split it into two layers) at the point where you want the effect to start. Then apply the effect to only that layer.

    Thanks.

    Splitting a layer didn’t work; when the layers changed, it would jump to the middle of the shatter. So I tried duplicating the layers, applying the shatter effect to the duplicate, and setting the in and out points of the layers so that it would seamlessly go from the layer to its duplicate. Lo and behold, it worked like a charm. Perhaps not the most convenient of ways, but it works well enough.

    Hi,

    I think I asked this same question about two years ago. The answer turns out to be pretty simple…

    Under Force 1, animate the Depth variable from a negative to a positive number (or vice versa) and that should send a wrecking ball through your layer.

    The problem is the effect defaults to shatter your layer the moment it starts. Only by changing the depth of the force element can you accurately animate when it occurs.

    Hope this helps,

    Lars
