  • Master Slider control other linear()

    Hello forum,

    How can I make a master slider to control 3 linear()?

    For example, I have 3 Radial wipe effect and set the completion using linear(time,0,1,0,100) each on same layer. <font face=”inherit”>How to link those linear() to Slider Control 0 to 100 all wipe starts in </font>sequence (<font face=”inherit” style=”font-family: inherit; font-size: inherit;”>wipe 1> wipe 2> wipe 3)</font>?

    Thank you,

    ilya

    To make the slider control the animation, you would not use time but slider value, and since you can animate the slider from 0-100 (same range as transition completion) you wouldn’t need a linear() to remap the ranges, this simple linked expression does it:

    effect("Slider Control")("Slider")

    But for the 2nd part of your question, it depends on what you mean by in sequence.

    Should they all react to the same slider, but delayed: the 2nd wipe 10 frames later and the 3rd wipe 20 frames later for example ?

    Or should the 1 slider control all 3, but the 2nd doesn’t start untill the 1st wipe is completed, and the 3rd wipe starts when the 2nd is completed ?

    Or is the slider not controlling the completion, but the delay ?
