RigtRect

RigtRect is short for rigged rectangle and it's basically a shape layer rectangle which spans between to layers.

Normal shape layer

Due to the fact that a RigtRect is made of standard shape layers with an expression rig applied you can very easely style the rectangle with different fills and strokes.

Add padding to your rigged boxes by using an "offset paths" effector.

Rounded corners work better if you use the rounding option of the rigged rectangle, not by using the "rounded corners" effector.

The RigtRect is also compatible with allmost every After Effects installation, even if the script is not installed on your machine. This makes it a perfect fit for Essential Motion Graphic Templates (.mogrt).

Anchor & Handle Layer

The anchor layer determines the point from where the RigtRect layer is scaled and the handle layer defines the point where the RigtRect spans to.

To keep the number of control layers as low as possible you can define the layer itself as its anchor layer. You then only need a handle layer for a working rig. The effect resets the anchor layer to itself.

Anchor Position

This option is only used by the RigtSource right now. Unless you choose Center, the RigtRect will allways been drawn exactly between the two control layers.
