LockNodes

Lock your nodes.
Sell the .blend anyway.

Lock your node groups behind a password before you share a .blend. Buyers see a placeholder instead of your real nodes — until they unlock it with the key you set. Works with Shader Groups, Compositor Groups and Geometry Nodes.

This addon is also available for free on kunemann.com. This listing exists purely as a way to support development — any purchase here is optional, and gratefully accepted.

Password lock

Lock any Shader, Compositor or Geometry Nodes group with the password you set once in preferences.

A real placeholder

Buyers see a flat, tinted group with an optional watermark text where your nodes were — not an error, not a blank socket.

Soft or hard lock

Soft lock hides the internals and restores them on unlock. Hard lock deletes them outright, with an optional local backup first.

One-click unlock

Anyone with the password rebuilds the original nodes instantly — unlock a single group or every sub-group at once.

Local password only

The master password lives only in your local Blender preferences, never in a shipped .blend. Unlocking always requires it.

Custom watermark

Tile your own text — "Full version on SuperHive", your studio name — across every placeholder, tiled and rendered as a real image.
