Node Color Cycler — Nukepedia

Node Color Cycler

This script adds hotkeys to quickly cycle the tile colors of selected nodes in Nuke.

Features:

- F10: Cycles between Red → Green → Blue → Default → repeat

- F11: Cycles between Pink → Yellow → Orange → Default → repeat

- F12: Cycles between Black → White → Default → repeat

Behavior:

- Each press advances the color by one step in the cycle.

- If the node color is not part of the cycle, it starts at the first color.

- The "Default" step resets the node’s tile color to Nuke’s standard grey.

Implementation:

- Colors are defined as normalized RGB values [0–1].

- A helper function `set_tile_color()` converts RGB to Nuke’s ABGR int format.

- The NodeColorCycler class manages the color cycles and hotkey bindings.

Usage:

- Place this file inside your ~/.nuke folder (or studio pipeline scripts folder).

- Nuke will automatically register the hotkeys (F10, F11, F12) on startup.
