Render AOVs
A position pass describes the actual position of the geometry represented by each pixel. ie, the origin if represented by geometry in the image, and is visible will have an RGB value of (0,0,0)

Tech Check
Before you submit a shot, run a tech check. This is the non-negotiable pass that catches pipeline and integration failures before a supervisor or client does.

Color Science
Color is not a file format, a LUT, or a “look.” It is light, filtered by human vision, measured into numbers, carried through cameras and software that each speak a different dialect, and finally forced onto a display that can only show a triangle of colors inside a larger world of what people can see.

Nuke Defaults
Out of the box Nuke's default configuration isn't very optimized for day to day work. Use these sensible Nuke default settings

Node Graph Structure
A Nuke script is a directed acyclic graph (DAG): nodes (vertices) connected by pipes (edges) that always flow forward — never in a cycle. That is not just computer science trivia. It is why your script can be evaluated in a clear order, cached, and handed to another artist without turning into a knot.

Lensing
As light passes through a camera lens, it does not stay perfect. The glass stack, aperture, coatings, and matte box all imprint artifacts on the image: soft focus falloff, dark corners, geometric warps, color fringes, flares, haze, and grain (or noise).

Motion Blur for VFX
Motion blur is the streaking that appears when something moves while the shutter is open. On a real camera it is an optical fact of exposure time. In VFX it is something you must match, not invent: wrong blur is one of the fastest ways to make CG, plates, and composites look fake.

Playback Tools for VFX
You need a player that can scrub image sequences (EXR, DPX) and movie proxies at speed, with color management you trust. Nuke’s viewer is fine while you work. For dailies, version flips, and “does this actually play,” people reach for dedicated playback.
