Using Position To Mask Gizmo for Nuke

Mark Spindler demonstrates another of his Gizmo creations for Nuke called Position to Mask which creates a spherical mask in 3D space perfect when rendering with a position pass in Nuke. MArk notes that this tool was inspired by a fxguidetv episode about District 9, in which Shervin Shoghian from Image Engine shows a similar tool that was developed for this film.
