A Nuke Gizmo for Depth of Field That Takes Transparency Into Account
This is a very quick walkthrough of a Gizmo I wrote it Python last winter. It lets the user easily add values to image channel isolated my user selected masks. A practical use of this, is manually adding depth values for transparent surfaces, as depth of field done in compositing does not take this into account.
It also gives the user options for which masks they would like to use, if they already have imported their beauty and mask images into the scene, as well as what image channel to display, without having to dive into the Gizmo itself.
