Hi, If I link an effect (say blur) to another (say scale) via an expression using the pick whip, can I offset the link? That is: if the scale paramaters go from 50% to 100% can I have the blur start at 0% and go to 50%? If not can I have some kind of "invisible effect" that has no effect but to which I can link other effects?
You can probably tell I am very new at this.
Yes you can. in your expression field after you pick whipped your scale property you should have something like that:
and you just have to add a -50 to offset it:
You can do math operation as long as the expression values are numbers:
even between two linked properties
this.comp.layer("your layer").transform.scale / this.comp.layer("your layer").transform.rotation
Hope that helps
Hi Sebastien. Many thanks. One more thing, how do I edit the expression field afterwards. i.e. I have put in a -50 offset but would like to change it to a -40 offset.
Many thanks, Matt.
Edited... Doh! I worked it out.
