Environment Variables That Mari Recognizes

FN_DISABLE_LICENSE_DIALOG

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

Note:  When this environment variable is set, a warning message is still displayed if no license is found.

FN_SUBSCRIPTION_LICENSE_DIR

Changes the license directory to an alternate location using the FN_SUBSCRIPTION_LICENSE_DIR variable.

Note:  On Windows, there is a known issue with user names containing non-ASCII characters causing licensing to fail. If a licensing error displays, try using the FN_SUBSCRIPTION_LICENSE_DIR variable. For more information, see Licensing Mari Non-commercial on Windows

MARI_APPLICATION_THREADCOUNT

Overrides the application thread count setting.

When the environment variable is unset, Mari uses all available threads.

MARI_CACHE

The location(s) of the Mari project files. This can be just one directory or several (to make caching faster). You should separate multiple path entries by a : (colon) on Linux and Mac, or a ; (semi-colon) on Windows.

Project directories must be permanent directories and not temporary locations as they contain important project file information.

If this variable is not set, Mari prompts you where to store the project files when you first launch it.

Note that when you set this environment variable, Mari takes its value and stores it in the CacheLocations.ini file (by default found in the .config/TheFoundry sub-directory of your home directory on Linux, or the .mari\TheFoundry sub-directory on Windows and Mac). Be cautious of changing this. The set of project locations must not be changed after project creation; doing so results in project corruption. . For more information please see Installation and Licensing.

MARI_COLORSPACE_USER_INTERFACE_MODE

Sets the colorspace mode Mari is using. You can set the following modes:

• 0 - Basic mode

This mode displays a limited amount of the colorspace options available in Mari.

• 1 - Default mode

This mode displays the standard colorspace options available in Mari.

• 2 - Advanced mode

This mode displays all the colorspace options available in Mari.

MARI_DEFAULT_ARCHIVE_PATH

The default path to load and save project archives.

MARI_DEFAULT_CAMERA_PATH

The default path to load and save cameras and projectors.

MARI_DEFAULT_EXPORT_PATH

The default path to export textures to.

MARI_DEFAULT_GEOMETRY_PATH

The default path to load geometry from.

MARI_DEFAULT_IMAGE PATH

The default path to load and save reference images.

MARI_DEFAULT_IMPORT_PATH

The default path to import textures from.

MARI_DEFAULT_RENDER_PATH

The default path to save renders such as turntables.

MARI_DEFAULT_SHELF_PATH

The default path to load and save shelf files.

MARI_FORCE_COLOR_MANAGEMENT

When set to 0, color management is forced off. When set to 1, color management is on.

MARI__ENABLE_LEGACY_COLOR_MANAGER_PALETTE

When set to 1, displays the Color Manager (View Transform) palette in Mari.

MARI_GIZMO_PATH

Nodes are exported from Mari as Gizmos in .mng files. Use MARI_GIZMO_PATH to specify a different directory from which to load Gizmos, in addition to the default Gizmos directory.

MARI_GIZMO_PATH accepts multiple values separated by a : (colon) on Mac OS X and Linux operating systems, or a ; (semi-colon) on Windows.

MARI_INSTALL_PATH

When you intend to launch Mari from Nuke, from the Mari > Launch Mari menu, you can set the environment variable MARI_INSTALL_PATH so that you don’t need to point to the Mari executable every time. For more information, refer to the Nuke<>Mari Bridge section.

MARI_LOG_FILE

The name and location of the Mari log file.

If this variable is not set, the log is saved to:

• MariLog.txt in the /home/<Username>/Mari/Logs directory on Linux and Mac, or

• MariLog.txt in the C:\Users\<Username>\Documents\Mari\Logs directory on Windows.

The path where Mari looks for baking preset files.

For more information, see Modo Render Settings

MARI_NAMEDFILEIMPORT_SEQUENCELIMIT

The maximum number of patches objects are allowed to have for the Named Files tab to appear on the Import Channel and Export Channel dialogs.

By default, the Named Files tab does not appear if you have more than 20 patches in your object, but you can change this using the Patch Cutoff preference.

You can use the Named Files tab to import or export individual files rather than a sequence of patches with the udim number (1001, 1002, etc.) in the file names.

MARI_OLD_PYTHON_INIT

When loading a script, if existing start-up scripts do not work correctly due to the load module order, you can revert back to the old behavior by setting the environment variable MARI_OLD_PYTHON_INIT to any non-empty string other than 0.

For more information, refer to the Loading a Script section.

MARI_SCRIPT_PATH

A list of paths to run scripts from.

MARI_SVT_ATLAS_LAYER_COUNT

Forces the Layer Count to a specific value that may not have been available through the Mari Preferences Dialog

Note:  This environment variable is targeted at MAC OS X users as the Layer Count preference is always disabled on this platform.

MARI_SVT_SUPPRESS_WARNINGS

This stops the SVT from displaying the warning dialog when the SVT properties may cause issues on the current hardware.

MARI_USER_PATH

Root of the default user path.

MARI_WORKING_DIR

The location of temporary Mari files, such as crash logs.

If this variable is not set, the files are saved to the same path as the log file.

SHOW_BASE_DIR

The path where Mari looks when importing images.

You can call these variables anything, and as long as you precede the variable name in the image import path with $ on Linux and Mac, or % on Windows. Mari replaces that part of the path with the value of the environment variable.
