Shape Cutter
 
 
 

Lets you create and manipulate simple shapes to add an alpha channel to an image. Because Shape Cutter only affects the alpha channel, you will not be able to see its effect unless you enable the alpha channel display in the FX viewer.

Requires an Input (RGB).

Produces an Output (RGBA).
