Forums Adobe After Effects Gaps appearing between layers when they’re moving around the screen


  • Gaps appearing between layers when they’re moving around the screen

    I have an “array” of 9 layers that are positioned like tiles, right up against each other without any overlap or gaps, like a big square divided into 9 small squares.

    These layers all move in complete unison, since they are tied to another separate layer that has two expressions on it to control size and position.

    The problem is when the layers start moving, little gaps start to appear between them.

    These gaps then get amplified by the motion blur effect (which is crucial for this project).

    How can I solve this issue and prevent these gaps from appearing?

    Have you tried nesting your nine layers in a pre-comp and then tie the pre-comp to your separate layer that uses the two expressions?

    That would probably work but unfortunately I can’t do that in this project.

    Each of these layers is pretty much the maximum image size AE will let me have, so I can’t create a comp that would be big enough for more than one of them.

    So you have a reason why your layers have to be that big? Do you not have the option of working around the size limitation by making a single pre-comp the largest allowable size and then placing your nine-layer array in that?

    I’ll start by saying that I know pretty much nothing about AE so I’m sure there’s a better way to do what I’m doing.

    My project is just a typical 3840×2160 resolution, but the effect I’m trying to achieve is quick camera movements over a great distance, enough to create a strong motion blur effect for a duration of a second or half a second.

    With my zero knowledge of AE the only way I could figure out how to do it is by actually creating an absolutley giant background layer, and moving that around (with a script that a great guy from this forum wrote for me).

    So I know this is ridiculous but each layer but each of these 9 layers are about 27000×15000.

    And again, the size is so big to help me achieve the movement speed, travel time, and motion blur that I’m looking for.

    If you know a better way of doing that, please enlighten me! 🙂

    Your response suggests that your layers don’t truly have to be that big. You’re just trying to avoid more work. Make a pre-comp as big as you can and put your nine layers in that. That should solve your visible separation issues during motion which is something that has to be fixed. Figuring out how to achieve the speed and blur you want is secondary. Ask 10 AE users how to pull that off and you may get 10 different answers, but none of the solutions should be difficult.

    Well if the speed and blur can be achieved in a smarter way then I wouldn’t need those 9 layers at all, I would just use one since they’re all identical.

    At this point my project is done except for this one bug, so if I can fix that instead of recreating everything in a new way it might not be the smartest solution but it would be the quickest one.

    Anyway, I’ll open a new thread asking how can I achieve this effect in a more effiecnt way and hopefully I’ll get an answer 🙂
