Allows you to set the script name and path. This field is completed automatically the first time you save the script.

Sets the default location where project files are saved. For example, if you only specify a file name in a Write node, the files are rendered to this location.

Click to set the project directory using an expression so that if the .nk file is relocated, the project directory updates automatically.

Adds a comment to the script, which is only visible in the plain text of the .nk file in the label field.

When enabled, all node connections are locked, making it easier to move nodes around the Node Graph without disconnecting them accidentally.

Sets the frame range for the script, which is used for nodes that don't include their own frame range controls.

When enabled, the frame range is locked so that adding new image sequences does not alter the frame range.

When disabled, adding new image sequences alters the frame range to encompass the new range.

Sets the project frame rate. Adjusting this control affects the Viewer's frame rate as well.

Sets the default format for the project.

When enabled, images are rendered at either the proxy scale or format as specified by the proxy type control.

Sets the proxy type when proxy mode is enabled:

• format - the proxy resolution is determined by the proxy format control.

• scale - the proxy resolution is determined by the proxy scale control.

Sets the proxy resolution when the proxy type control is set to scale.

Sets the proxy resolution when the proxy type control is set to format.

Sets when Read nodes fallback to the proxy resolution when proxy mode is enabled:

• never - the proxy resolution files are never used.

• if larger - the proxy resolution files are used if the files are equal to or larger than the scaled size.

• if nearest - the files closest to the scaled size is used.

• always - the proxy resolution files are always used.

When enabled, the script is saved as a LiveGroup script, allowing you to nest it within other scripts using the LiveGroup node.

Sets which colorspaces are available to Read/Write nodes and Viewer processLUTs in the current script.

• Nuke - only the Nuke root colorspaces are available.

• OCIO - the specified OCIO config colorspaces are available as well as Nuke root colorspaces.

When enabled, any Viewers using the GPU to process data also compute OCIO data on the GPU, rather than the CPU.

Note:  The GPU path in OCIO is not completely accurate, so you may see banding or color inaccuracy when using OCIO on the GPU.

This control only affects the Viewer when the Preferences > Panels > Viewer (Comp) > use GPU for Viewer when possible is enabled.

When color management is set to OCIO, sets the configuration to use and populates the default LUT settings appropriately.

Selecting custom allows you to reference a custom OCIO color file using the custom OCIO config control.

When OCIO config is set to custom, enter the file path and name of the .config file.

default LUT settings

Sets the working colorspace within Nuke. Files are converted to this colorspace when they are read into Nuke. At render time, the files are converted from this colorspace to the selected output colorspace.

If color management is set to Nuke, this control is always set to linear.

Sets the default LUT for postage stamps, OpenGL textures, and all non-Viewer image and color displays.

If your Viewer process is a simple LUT, set this control to the same LUT, although sRGB provides an acceptable result is most cases.

Note:  When color management is set to OCIO, these colorspaces are grouped by the Display and saved in the Project Settings.

Other colorspace types are grouped by the family name.

Sets the default LUT used when reading and writing image data containing 8 bits.

Sets the default LUT used when reading and writing image data containing 16 bits.

Sets the default LUT used when reading and writing image data containing Cineon/DPX style log data. These files are typically 10-bit.

Sets the default LUT used when reading and writing image data containing floating point values.

Displays the lookup curves used to convert between file/device colorspaces and the linear working colorspace used for internal operations.

Note:  SLog has been deprecated in favor of SLog1, but remains in the list to ensure backward compatibility.

Click to add a new curve to the list of LUTs.

Click to reset any points that you have adjusted on a curve to their default position.

Click to delete a custom curve from the list of LUTs. You can't delete the default LUTs that ship with Nuke.

Click to add a new view to the script.

Click to remove a view from the script.

Note:  You cannot remove a view if it is the only view in the script.

Click to move a view up or down the views list. The view at the top is the first listed above the Viewer.

Lists all the views currently in the script and the color associated with each view.

Note:  The colors are only visible in the script when Use colors in UI? is enabled.

Sets the view that is loaded by default when the script is loaded.

Click to automatically create left and right views for stereographic projects.

When enabled, the views in the script are displayed as buttons above the Viewer.

When disabled, the views in the script are hidden in a dropdown menu.

When enabled, the colors specified per view in the views list are displayed above the Viewer and in Node Graph for clarity.

These functions run when a script is loaded.

These functions run when a script is saved.

These functions run when a script is closed.

Live Group Callbacks

These functions run after a LiveGroup node goes from the Published state to the Local state.

These functions run before a LiveGroup is published. If this callback throws an error, the publish operation is interrupted.

These functions run after a LiveGroup is published.

These functions run after a LiveGroup is reloaded.

Allows you to specify a directory from which to read font files.

When enabled, all the system fonts are available in addition to those that ship with Nuke.

When disabled, only the fonts that ship with Nuke are available.
