Official Build 2018.22800 - May 11, 2018[edit]

New Features[edit]

Major New Additions[edit]

  • This version has substantial speed optimizations. Many of the speedups focus on using python expressions in parameters, and significant improvements to startup and project launch time have been made.
    • Optimized Python Expressions to speed up commonly used python expressions.
    • Caching expression results so they don’t need to recalculate. If a node needs to cook, only the parameters that *may* have changed will be re-evaluated.
    • Optimized startup and launch process.
    • Perform CHOP has new parameters to monitor how many expressions are optimizes and cached.
  • Dongle-based Component Privacy - Support for CodeMeter dongles to add Privacy to components and license their use.
    • Developers can now create CodeMeter dongles that will license the component to run (cook). These dongles do not give access to the networks inside, they just allow them to run on any licensed TouchDesigner or TouchPlayer.
    • A 'Developer Dongle' is used to make a component private and continues to give developer access to the networks inside the component.
    • Managing privacy with a Developer Dongle can be accessed through python or the Privacy Dialog (right-click on component and select 'Privacy...').
    • Setting up Developer Dongles is a service provided by CodeMeter and handled between the Developer and CodeMeter.
    • A Developer Dongle requires a TouchDesigner Pro license but no additional fees charged by Derivative.
    • Contact us for further details about Developer Dongles.

COMPs - Components[edit]

  • ext.parentshortcut is deprecated: Do not use this form any more. Use parent.parentshortcut.
  • tdu.split() added - Returns a list from a space separated string, allowing quote delimiters.

string: any Python object... will be evaluated as str(string), so parameters will work. eval: if True, convert any valid Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.


  split('1 2.3 None fred "one '2'" "[1,2]"')

yields ['1', '2.3', 'None', 'fred', "one '2'", '[1, 2]']

Backwards Compatibility[edit]

  • BACKWARDS COMPABITIBILITY WARNING - The UDT protocol on network DATs and CHOPs has been deprecated and will be removed in future builds. The protocol has been abandoned by it's creators and seems to crash on Windows 10, as such we are removing support for it. Currently it will just create a warning when nodes use it.
  • BACKWARDS COMPABITIBILITY WARNING - Default for Python-type custom parameter is now None instead of empty string.
  • BACKWARDS COMPABITIBILITY WARNING - Now Python None object to string casts to empty string instead of 'None' within parameter evaluation for operator parameters only. Will work with list objects as well.
  • BACKWARDS COMPABITIBILITY WARNING - Fixed Text TOP and Text SOP evaluation to be consistent with other string parameters which convert lists objects to space separated text.
  • BACKWARDS COMPABITIBILITY WARNING - The Window COMPs .width and .height members gave inconsistent results when borders were enabled but borders aren't included in the size. They now always give the size of the window, including borders.
  • BACKWARDS COMPATIBILITY WARNING - Parent Shortcuts - ext.parentshortcut is deprecated: Do not use this form. Instead use parent.parentshortcut. A warning is issued now.
  • BACKWARDS COMPATIBILITY WARNING - The seed for the Sort DAT is now floating point vs integers. You can use integers but the random ordering for 2. is different now vs 2 before, for example.
