    Hi everyone,

    I’m trying to apply a drop shadow and cc page turn to a comp, but when I apply both, the drop shadow becomes a cloud of dots and I have no idea why. I thought it might have to do with continuous rasterization, but I’m not sure.

    Here are the details of the comp:
    (I’ve attached an image of what is happening)

    The white rectangle in the middle, and all the graphs on it, are nested in a composition. The white rectangle was created in Illustrator. When I apply a drop shadow to the composition that contains the rectangle, I get the dot cloud. When I apply the drop shadow to the rectangle inside the comp, it looks fine in both the rectangle comp and the main comp. However, when I apply CC Page Turn to the comp, the drop shadow changes into the dot cloud.

    One interesting thing is that when I move any of the drop shadow control sliders, the dot cloud changes to a proper drop shadow as long as I am moving the slider.

    I’ve never seen this before and was wondering if anyone could tell me what was going on!

    Thanks everyone!

    The white rectangle is in a pre-comp. I’m sorry – I should have been clearer about that.

    The dot cloud appears when I apply the drop shadow to the rectangle inside the precomp and when I apply it to the precomp itself.

    Thanks for the suggestion. However, I tried turning Open GL off and it didn’t help. I also played around with the various settings but it didn’t help.

    The problem seems to be with this particular composition. I just remade the comp from scratch, applied the same effects in the same order, and dropped it into my main comp with no problems. I have no idea why the dot cloud appeared, but I was able to rather inelegantly workaround.

    In any case, thank you so much for your help!

    Seems to me that blending mode was set to Dissolve instead to normal…

    Ah ha! That was exactly the problem. Thank you Mato. I shan’t make that mistake again!
