"Unused Node Cleaner" allows you to clean your blueprints from unused nodes that someone left somewhere and are still there to distract you.

WARNING: While the "Hide Unused" toggle is on, the plugin will disable the "Hide Unrelated" feature as the plugin uses the same engine functions to make the nodes fade out.

Unused Node Cleaner can be purchased on the Unreal Engine Marketplace.

The plugin adds two buttons to different blueprint/graph editors that allow cleaning them. Find more information and see it in action on the Getting Started wiki page.

You can find answers to some frequent questions on the FAQ.

And if you have some problems using the plugin or want to give some feedback, please create a new Issue.
