The location where Nuke saves all recent images flipbooked with FrameCycler.

If this variable is not set, the location is determined by NUKE_DISK_CACHE.

This points to the directory that contains bin/framecycler.

If you want to use a different version of FrameCycler than the one shipped with Nuke, you can use this to set the base directory of FrameCycler. This points to the FrameCycler binary.

Allows you to specify where Issue Reporter dumps are saved by default.

By default, if you have installed a temporary license, Nuke displays a dialog at start-up alerting you to the number of days remaining. If you want to disable this behavior, you can set either of these environment variables to 1 to suppress the warning message about imminent license expiration.

NOTE:  You still get a warning if no license is found, for example if you only have a Nuke license but you try to run NukeX.

The location of the Nuke license file (a plain text file called nuke.lic), if the following recommended location is not used:

On Mac OS X and Linux:

/usr/local/foundry/FLEXlm

On Windows XP:

drive letter:\Program Files\The Foundry\FLEXlm

On Windows Vista:

drive letter:\ProgramData\The Foundry\FLEXlm

Breakpad crash reporting allows you to submit crash dumps to The Foundry in the unlikely event of a crash. By default, crash reporting is enabled in GUI mode and disabled in terminal mode.

When NUKE_CRASH_HANDLING is set to 1, crash reporting is enabled in both GUI and terminal mode.

When NUKE_CRASH_HANDLING is set to 0, crash reporting is disabled in both GUI and terminal mode.

When working on large images, Nuke may need to free up memory during rendering. When this happens and NUKE_DEBUG_MEMORY is set to 1, Nuke prints the following information to the console:

Memory: over maximum usage, trying to reduce usage from 1GB to 924MB.

If this variable is not set, you cannot see the debug memory messages.

Note that here, KB, MB, GB, and TB mean units of 1000. For example, 1MB means 1,000,000 bytes.

The location where Nuke saves all recent images displayed in the Viewer. Ideally, this should be a local disk with the fastest access time available. It should also have enough space for the maximum flipbook cache size.

If this variable is not set, the location is determined by the flipbook cache setting in the Preferences. By default, this setting points to NUKE_TEMP_DIR.

The maximum size the flipbook cache can reach (in gigabytes).

If this variable is not set, the location is determined by the flipbook cache size setting in the Preferences.

On Linux, this is the location Nuke uses for temporary files while reading PIZ-compressed .exr files. This environment variable is only relevant on Linux.

If this variable is not set, the location is determined by NUKE_TEMP_DIR.

The location that Nuke checks for available font files when the Text node properties panel is opened.

The import nuke function checks-out a nuke_r render license by default. If you want to use Nuke interactively, and you have a nuke_i license, set this environment variable to 1.

See Nuke as a Python Module for more information.

When crash handling is enabled in GUI mode, this allows you to control whether reports are automatically submitted or not:

When NUKE_NO_CRASH_PROMPT is set to 1, crash reports are submitted automatically without displaying a crash reporter dialog.

When NUKE_NO_CRASH_PROMPT is set to 0, Nuke always displays a crash reporter dialog before submitting a crash report.

The location where files related to Nuke customizations are stored. For more information, see Loading Gizmos, NDK Plug-ins, and Python and TCL Scripts.

The location where Nuke saves any temporary files that do not have a particular place defined for them.

This is also where the flipbook cache setting in the Preferences defaults to.
