    Hello

    I applied a Point Control to a solid that should move a text line in both directions and a shape layer vertically in another comp.
    When I turn the point control watch on and move it the elements move accordingly and the first KF is created.
    If I move the cursor to the right and move the point control a new KF is created but the elements don’t move.
    All the KF I create to the right show the new position of the point and interpolate normally but the elements keep stuck to the first KF position.
    If I move the cursor to the left and move the point control the elements move with the point and a new KF is created but now the KF to the right stops working and the elements don’t animate.

    I applied this expression to the position of the text:

    comp(“Animatic1”).layer(“PosicaoTexto”).effect(“Point Control”)(“Point”)

    And this one to the Y position of the shape layer:

    comp(“Animatic1”).layer(“PosicaoTexto”).effect(“Point Control”)(“Point”)[1]+30

    Thank you very much

    comp("Animatic1").layer("PosicaoTexto").effect("Point Control")("Point")

    comp("Animatic1").layer("PosicaoTexto").effect("Point Control")("Point")[1]+30

    If your expression is in a precomp that doesn’t start at time zero in the main comp, you probably need to compensate for that by doing something like this:

    L = comp(“Animatic1”).layer(thisComp.name);
    comp(“Animatic1”).layer(“PosicaoTexto”).effect(“Point Control”)(“Point”).valueAtTime(time + L.startTime)
