Hey folks, here is Part 1 of my new VFX Bites series: Lens Distortion Workflow, below are the attached files. This introduced the NEW lens distortion node updated since Nuke 11 and goes into detail the process of overscan within Nuke. Part 2 and Part 3 are coming with proper overscan/reformat pipelines for Maya and Houdini rendering.
