Search TipsExample Nuke Scripts
This section pulls together and organizes the Nuke (.nk) scripts available to you throughout the help to ensure you can access them easily. The following video explains how to get the scripts into Nuke if the script links are disabled, and how to download the more complex examples.
The blue script links allow you to load the scripts into Nuke directly, but there are a few setup steps. If you just want to display a script to copy/paste it into Nuke manually, click the 
button. Additionally, some scripts and examples can be downloaded directly.
Note: Loading example scripts only works if you launched the help from Nuke and have set documentation source to local in the Behaviors > Documentation tab of the Preferences.
See Using Script Links for more information.
Using Script Links
The auto-links for the scripts in this help only work when Nuke and the help files are linked by the helpCommandRequestHander. To enable the links:
| 1. | Launch Nuke. |
| 2. | Navigate to the Preferences > Behaviors > Documentation tab and select source > local. |
| 3. | Add a node to the Node Graph and click the ? in the node's Properties panel. |
The help available for that node displays.
| 4. | Navigate to Example Nuke Scripts in the help table of contents on the left of the screen. |
| 5. | Click the required link to auto-load the script into the Nuke session. |
Note: If you close Nuke or the help, that session link is broken and must be re-established.
