This Nuke helper script automatically creates a versioned copy of the currently open .nk file whenever a Write Node finishes rendering.
Just hit render, and a copy of your Nuke script will be saved along with the render in the 'render_scripts' folder, creating a backup of every rendered version.
Installation:
1 . Copy 'AutoSaveRenderScript.py' to the .nuke folder in C:\Users\%username%\.nuke (Windows)
2. Add this line to menu.py
import AutoSaveRenderScript

How it works:
Listens to Nuke’s addAfterRender callback.
Reads the render path from the active Write node.
Builds a render_script folder inside the Write node’s output directory.
Creates a clean script name from the render filename (ignoring #### or %04d).
Copies the current Nuke script (.nk) into that folder using the naming convention:
{base_name}_script_v01.nk
{base_name}_script_v02.nk
{base_name}_script_v03.nk
(Auto-increments version numbers instead of overwriting.)
Saves a copy without interfering with your open session in Nuke.
Works with image sequences (####, %04d) or movie outputs (.mov).
Ensures reproducibility of renders by archiving the exact script version.
The script must be saved on disk before rendering — it cannot copy an “Untitled” session.
