Privacy option in TouchDesigner Pro

The Privacy option blocks recipients of a .toe file from editing networks in a .toe file, including the original author. This will protect the contents of the .toe file.

In TouchDesigner, under File -> Save Project .toe Private, you can save a separate private version of your session. Anyone who loads this .toe, will only open a control panel in a floating window, with no networks visible. When you press the Esc key over the window, it will just expose the window borders, if not already exposed. From there the user can close the window and application through the regular window title bar buttons.

The Privacy option can be set in TouchDesigner Pro only.

To hide image, movie, audio and other media that you embed in the file use the Virtual File System.
