  • How to create an active but transparent 3d mask?

    Hi everybody!

    I´ve got a question concerning 3d Masks in After Effects.

    I built a “3D” Cube in After Effects (took 3x 3D-planes: 1 front, 1 side, 1 top)

    And now i need to let this Cube “grow” out of a transparent ground.

    So, i dont want to see the ground-plane and the cube while beeing below the ground-plane but everything which is above the ground-plane and then animate the Y-position of the Cube to let it “grow” out of ground.
    Hope u guys know what i mean 😉
    Thanks a lot!
