Wiggle Expression

[Steve Roberts]

Set up the amplitude (amp) as a variable, and link it to an animated “expression controls” slider effect in the same layer.

Apply the expression controls effect, using a slider. Make it visible in the timeline. Apply the wiggle expression with a value for freq, but leave amp as is, and write amp= ; in a line above the expression. With the cursor in the space after the = , pickwhip to the slider.

Now the amp value is determined by the slider value. Animate the slider value, and the amplitude of the wiggle will follow.

Wow, that is great.

And implementing the slider was a snap. Now I can see how it can be done easily.

Thanks.
