    Hello! The 3D head layer is inside Comp1 and has X, Y and Z rotation that will be controlled by position and rotation of a 2D null in Comp2:

    3D head in Comp1 2D null in Comp2
    X rotation ———————- Y position
    Y rotation ———————– X position
    Z rotation ———————- rotation

    When I pickwhip each left item to its correspondent item at rigth, the 3D head turns to a strange position. The 2D null WORKS, but in an akward way.

    I suspect it would need toWord or fromWord expressions, because the head and the null are in different comps and one is 3D, the other, 2D. But when I send toComp or toWorld any of those properties, i.e, the transform.yPosition, I get the error:

    “First argument to toComp must be a vector of length 2 or 3”

    QUESTION
    How can I make those 3 connections?

    Thanks.
