  • weird 3d layers behaviour

    Posted by Jim Dodson on June 3, 2009 at 7:55 pm

    I’ve built a tunnel (similar to Andrew Kramer’s 3D tunnel) made up of several “walls” and “floors” and “ceilings” all of which are a jpeg of a stone wall.

    All is good so far.

    At the far end of my tunnel there is a wall (the same jpeg) and beyond that wall in “z” space there is a movie layer (also a 3d layer).

    The problem is: The movie layer is visible eventhough it should be invisible because there’s a wall in fornt of it — I’ve sent the movie layer deep deep deep back in z space and it remains visible… (as if it were in front of the wall — the wall layer should obscure the movie layer!!

    Anyone ever have similar issues as this?!!

    Here’s my workaround…

    I made a duplicate layer of the back wall — pushed it back a tad in z space then — replaced that duplicate wall jpeg with my movie (holding down option as I dragged it in)…

    That new layer is properly obscured by the wall layer —

    Nope — I just removed every 2D layer — It feels like a genuine bug in After Effects…

    I looked in the “TOP” view and the movie layer is clearly “behind” the back wall…. Yet the back wall refuses to obscure the distant layer….

    In addition to 2D layers, some other things can interfere with 3D layers interacting as you would like. There’s a list and explanation in the “How render order and collapsed transformations affect 3D layers” section of After Effects Help.

    Remove any Layer Styles from the 3D layers.

    Yes, as Darby says, layer styles are one of the 3D “bin breakers” that force groups of 3D layers to be rendered separately. (They’re #2 on the list of such things in the page that I pointed to in my previous post.)

    Thanks Darby & Todd —

    Yes indeed– even after I “solved” the problem, when I moved layers around in the stacking order (like above some text set to “3d” and layer styles added, the problem came back… Thanks for being pointed to that link Todd…
