Customizing Preferences
Fusion Studio’s preferences configure Fusion’s overall application default settings and settings
for each new composition. Although you access and set these preferences through the
Preferences window, Fusion saves them in a simple text format called Fusion.prefs.
These default preferences are located in a \Profiles\Default folder and shared by all Fusion
users on the computer. However, you may want to allow each user to have separate
preferences and settings, and this requires saving the preferences to different locations based
on a user login.
To change the saved location of the preferences file requires the use of environment variables.
Setting the Preferences Location
When you fist open Fusion, the environment variable FUSION_PROFILE_DIR defines the folder
that contains the Profiles folder. If this variable defines a valid path, then the preferences are
saved to this folder. If the FUSION_PROFILE_DIR does not exist, then Fusion attempts to create
it. If it cannot create the path, then the preferences are stored in the default location:
AllData:\Profiles.
Typically, all users share the same preferences. Fusion saves these default preferences in the
FUSION_PROFILE_DIR\Default folder. If the FUSION_PROFILE_DIR environment variable
exists and has a valid name, then Fusion loads preferences from FUSION_PROFILE_DIR\
[name] instead.
If you want each user to save separate preferences within their home folder, you must create a
login script that runs when each user logs in to their computer to set the environment variable
FUSION_PROFILE_DIR to:
On macOS: FUSION_PROFILE_DIR = z:\Application Data\Fusion
On Windows: FUSION_PROFILE_DIR = z:\Application Data\Fusion
On Linux: FUSION_PROFILE_DIR = z:\Application Data\Fusion
When you open Fusion, it loads preferences from the appropriate path.
Creating a Master Preferences File
When working with multiple Fusion users in a studio, you may want to standardize on a few
settings. Using the FUSION_MasterPrefs environment variable, you can create one or more
site-wide preferences in addition to your local personal preferences.
FUSION_MasterPrefs must contain the full path to at least one preferences file. If you have
multiple preferences paths, separate them using semicolons. Fusion does not write to these
prefs files, and they may contain a subset of all available settings. You may change settings in
these files and use them only where local prefs do not already exist unless you set the
Locked flag.
Locking Preferences
If the line “Locked = true,” appears in the main table of a master file, all settings in that file are
locked and override any other preferences. Locked preferences cannot be altered by the user.
