    How can I rack focus my 3d Camera between two different expressions I am using for focus distance?

    PS — I want the “rack focus” to be a smooth transition over 20 frames or so….

    Hi Jim,

    Have you considered using an expression to link your focus distance
    to a null object and then animate your null to create the rack?

    Here is a link that explains it-
