Free Nuke Gizmo: P_Mask Position Pass Masks (franklinvfx)

Overview

P_Mask by franklinvfx (F VFX) is a Nuke gizmo to create quick masks using the data contained in a World Position or Ref Position render. The center of the mask is set with a 2D Position knob rather than a color picker, so it can be placed precisely regardless of the channel viewed, and the shape can be a sphere or a cube.

An overlay mode, 3D-space visualization and built-in unpremult and premult help keep edges clean. The gizmo is a free download from GitHub.
