  • Creating a Iris Blade

    Posted by Bram Rusman on November 7, 2012 at 10:23 am

    I’ve searched for this expression, but I can’t find it here.

    I have six 3D layers. Each layer is rotated 60 degrees in Z space. What I’m trying to achieve is a Iris blade transition. I have a 3D Null in the center of a comp. I’m trying to find a expression to rotate the Z-axis of the Null to drive the X position of the 3D layers. So that the layers move like a Iris Blade with a hexagon in center.

    Thanks in forward!

    try this on the z rotation of the blades:

    value+thisComp.layer(“Null 1”).transform.zRotation

    change”Null 1″ to the name of your null.
