    Hi all i was was wondering if anyone has come across these expressions before.
    Basically its a kids pop up book but i want to automate all of the layers within the page (the popups) based upon the page turn.
    So say the page goes from a rotation of 0 to 180. I then want all of the inside layers to change their orientation (on x or y) by 90. Only reaching the 90 degree limit when the 180 page turn has completed if you get my drift.

    Any thoughts on this before i get muddy?

    all help appreciated

    regards
    chris

    An expression as you described would work by just pickwhipping the the orientation of the layers to the rotation of the page and dividing by 2
