I worked on a project making three 3D bar graphs which would grow. I wanted the text of the item being measured to actually sit on top of the bar graph as it moved. In doing so, I ran into some issues with the text changing size as the bar grew, rather than it appear as if it was just sitting on top.
I could have easily animated the text to move with the bar, but I wanted to expand my knowledge and figure out how to make it work. After two days of math, reasoning, and trial and error, I got the desired result. I decided to share the experience with YouTube and make a tutorial on how to do this effect and offer a free preset to anyone who would want to do the same.
To download the preset, click the file sharing box on the right and download. To install it, open your After Effects program files and drop the preset in your Presets folder.
To use the Scale-to-Position preset, make one layer called “front.” Make an invisible Null Object called “Multiplier” with a “slider control” effect in it. Apply the “Scale-to-Position” preset to the layer you desire to be controlled. The “front” layer will be the one you use to control. Follow the formula in the tutorial to make sure your multiplier is the correct value.
[UPDATE] To simplify the download of the preset for Flash-incapable devices, I’ve made the following link just for you! Download
