Free Nuke 12 Gizmo: IBK Color Master Clean Plate Generator (Shubham Soni)

Overview

Shubham Soni's IBK Color Master lets you quickly create green or blue screen clean plates and defect maps using the IBKColour stack method. You pick the screen colour, adjust darks, lights and erode while viewing without the patch, and optionally exclude fine details with a mask input.

Patch steps then fill the screen, and a patch roughly option covers any remaining areas. Nukepedia lists it for Nuke 12.0 or later, and it is free with a Nukepedia account.
