Getting Help

Nuke features several forms of help, in a variety of locations.

Viewing Tooltips

Most controls offer concise instructions in the form of tooltips. To display the tooltips, move your mouse pointer over an interface control or a node parameter.

To view a tooltip for a node, move your mouse pointer over the ? icon in the node's Properties panel.

Viewing the Context-Sensitive Online Help

The context-sensitive online help includes a comprehensive description of each node and its parameters. To display these descriptions in your default web browser, click the ? icon in the node's properties panel.

Selecting the Help Source

In Nuke, the context-sensitive help content may differ depending on what you've selected as the help source in the Preferences.

To select the help source:

1.   Press Shift+S on the Node Graph to open the Preferences dialog.
2.   Go to the Behaviors > Documentation tab.
3.   Set documentation source to:

local - Use Nuke's built-in help system. This is included in the Nuke installation and does not require an Internet connection.

Note:  When you click ? in a node's Properties panel, Nuke searches the following locations for HTML files with the same name as the requested node (for example, blur.html):

1. Directories contained in the NUKE_PATH environment variable.

2. The /$HOME/.nuke and /$HOME/.nuke/Documentation directories.

3. Your local plugins directory.

• On Windows, this is either C:\Program Files\Common Files\Nuke\11.3\plugins\ or C:\Program Files (x86)\Common Files\Nuke\11.3\plugins\

• On Mac, this is /Library/Application Support/Nuke/11.3/plugins/

• On Linux, this is /usr/local/Nuke/11.3/plugins/

4. The Nuke installation directory.

foundry - Use the help system available on our website. This contains the most up-to-date information, but requires an Internet connection.

Note:  On Windows, you may have to add a firewall program or port exception to view the most up-to-date help from our website. If the connection is blocked, Nuke falls back to the local copy.

custom - Use your own custom help system.

4.   If you set documentation source to local, you can either:

enable auto port to automatically assign a free documentation server port, or

use local port to specify a local documentation server port manually and port range to define a range of ports to attempt. Typically, the local port value should be 1024 or higher. Setting the value to 0 causes a port to be automatically assigned.

Note:  To be able to use the online help from multiple sessions of Nuke running at the same time, you must enable auto port.

5.   If you set documentation source to foundry:

the foundry host field displays the documentation server host address.

use foundry port to specify the documentation server port.

6.   If you set documentation source to custom:

set custom host to your documentation server host address. This must be an Internet Protocol version 4 (IPv4) address.

use local port to specify a local documentation server port. Typically, the local port value should be 1024 or higher. Setting the value to 0 causes a port to be automatically assigned.

use custom port to specify a custom documentation server port.
