wiggle positive only


#1

i would like to randomize exposure effect to have a desired flicker look using wiggle exposure amount, unfortunately it wiggles back and forth between negative and positive values.

how do i clamp it to just the positive values?

regards

Try this


var myWiggle = wiggle(5,100);
var delta = myWiggle - value;
value + Math.abs(delta)

replace “wiggle(5,100)” by whatever wiggle you like. It only works with 1d values like transparency or exposure.
