Rotate a normal pass with an Axis and output a clamped grayscale light response for simple normal-based shading in Nuke.
Normal Light takes a chosen normal layer, applies the world matrix of a linked Axis as a ColorMatrix, then keeps the red channel as RGB (and alpha) and clamps it. The result is a grayscale image driven by the rotated normals.
Use it when you need a quick directional light or shading cue from an existing normal pass without a full 3D light setup. Point the Axis rotate control to change light direction; pick the normal layer on the gizmo.
In the node graph it sits on a beauty or utility branch: feed normals in, rotate, and merge or grade the output as a light wrap, fill, or isolation matte. Behavior is fully 2D after the matrix step—no camera or geometry required beyond the normal data you supply.
