Select a Layer and click the Bendy Nulls icon to run the script. Bendy Nulls will apply a CC Bend It effect to the Selected Layer with Global expressions applied to the Start and End points. It will then generate and parent two new Null Objects which will control the Start and End points of the CC Bend It, allowing the Selected Layer to be moved within the Composition whilst maintaining the CC Bend It effect.

When working with Raster layers a Grow Bounds effect will also be added to the artwork which will allow the Raster layer to bend further than its original Bounding Box. The value of the Grow Bounds contains an expression which calculates a value based on the positioning of the Start and End nulls, however if the artwork layer is Scaled this value may need to be adjusted to increase the Bounding Box further to compensate for the change in Scale.
