    Hi!

    When I alpha matte an object in cs6 there is still a thin line visible of the lower object, on the edges (sorry if confusing 🙂 )
    I could draw a mask , but the upper objects are sometimes complicated.
    Does anyone know a way to fix this?

    Thanks a lot!

    Can you post a still/screen grab of the issue- a picture is worth 1000 words…

    Well is your matte big enough?

    It’s a bit hard to see like this, but there’s a very thin line around his body. It appeared when i alpha matted a texture with the illustrator shape of his body.
    thanks!

    The texture underneath is bigger than the shape above, if that is what you mean

    How are you using the shape as a matte- track matte or using Channel filter?

    Try using Remove Color Matting Effect.

    Though it helps when we use effects that creates transparency but you can give it a try as Alpha Track Matte also creates the transparency.
