I would like to create a flexible box system.
Inside a 1920x1080 comp, I have three rectangular solids next to one another (640x1080)³. My goal is to change the width of one of the boxes and having the others auto adjust. For example if the first box scales horizontally to 800 px, I want the other two boxes to drop down to 560 px in width. Is there a script or plug-in that automates this process?
This has been done before. Pretty straightforward with some scale expressions. It works better with two nulls as separators between the boxes, as the calculations from several sliders become non-intuitive real fast.
