Official Build - 2019.10000 Series[edit]

New Features[edit]

Major New Additions[edit]

Unicode Character Support

  • Unicode - TouchDesigner now supports unicode everywhere. This allows the use of characters beyond standard 128 ASCII characters and adds builtin text support for most of the world's languages.
    • Use unicode almost anywhere you can type a string
    • File names and file paths can now contain unicode characters
    • DATs can now accept unicode characters directly
    • Text TOP and Text SOP accept unicode characters directly
    • Parameters can now contain unicode characters
    • Python can use unicode characters where supported
    • Some parts of TouchDesigner must still use standard alphanumberic characters, such as Operator names, Channel names, Custom Parameters, Custom Attributes.

Rigid-Body Dynamics

  • Physics - A new group of Dynamics Components now support hard-body physics simulations using Bullet Physics Library.
    • Bullet Solver COMP - Acts as the physics simulation solver.
    • Actor COMP - Holds geometry that is acted upon by the physics simulation.
    • Force COMP - Applies forces to Actor COMPs that specify them.
    • Impulse Force COMP - Applies impulse forces to Actor COMPs, which are forces that happen in an instant.
    • Constraint COMP - Constrains Actor COMPs together in 3 ways i) Point To Point ii) Hinge iii) Slider.
    • Bullet Solver CHOP - Extracts information from a Bullet Solver COMP or Actor COMP as channels that can be manipulated in CHOPs and then fed back into the simulation using the Bullet Solver COMP's 'Feedback CHOP' parameter.

FBX and USD Support

  • FBX COMP - New Component that loads FBX files as a network.
    • Allows for non-destructive updating of FBX assets while keeping network customizations.
    • No longer converts to intermediate .tog geometry format.
    • Support for lights, cameras, groups, merging geometry
    • Supports Direct to GPU
    • Separate parameter page for embedded animation control

  • Both COMPs have the option to generate Actor COMPs instead of Geometry COMPs in the FBX/USD network for use with the Bullet Solver COMP.
  • Import Select TOP, Import Select CHOP, Import Select SOP - These new operators work inside FBX COMPs and USD COMPs to extract textures, animation channels, or geometry meshes from the imported FBX/USD hierarchy into individual operators.

Custom Operators and C++

  • Custom OPs - Now C++ OPs you create have a new API allowing them to act like regular built-in operators. This includes giving them their own custom names and having them available in the OP Create Dialog under a new 'Custom' tab.
  • C++ DAT - The DAT family finally gets a C++ operator to create DAT Custom OPs as well.
  • Non-Commercial licenses now work with CPlusPlus OPs and Custom OPs, they no longer require a Commercial or Pro license.

Widgets User Interface Toolkit

  • Widgets - A new set of UI components for building control panels, performance interfaces, applications and systems. Designed to be modular and updatable, this new architecture is fully customizable and extendible and will be TouchDesigner's primary UI toolkit going forward. Widgets use python under the hood and the old tscript-based TUIK has been removed and deprecated.
  • This first release of Basic Widgets can be found in the Palette under UI > Basic Widgets. In the future there will also be a more advanced widget set for system builders.

Palette Improvements[edit]

  • Palette:kantanMapper - Improvements
  • Palette:moviePlayer - Improvements
    • Added option to enable/disable roller wheel zoom and mouse left/middle click/drag pan/zoom controls.
    • Added 'Go Back to Previous Movie' pulse button parameter.
    • Added extension functions so you can open a movie at a specific time (seconds) or cue number, and optionally play/pause

GoToMovieFile(mvfilepath, time=None, play=-1) GoToMvSpec(mvspec, cue=None, time=None, play=-1, selectcue=-1)

    • Added function to get properties of movie secretly: GetMovieProperties(filepath)
    • movieEngine - Click/drag on image to scrub. Shift click/drag to scrub and pause. Middle click to pause/play.
    • You can zoom into the movie image using (like in the network editor) the roller wheel, and left and middle buttons to pan/zoom. Zooming up-close, the pixels become discrete squares, and their values are displayed at the bottom right. Roller wheel zoom is off by default.
    • Control Panel Always On - on by default now.
    • Contents can adapt to any compoennt size.
    • Specify height of each control strip.
    • Movie can be behind or above controls.
    • Can now output mvspec.tox for later use with a moviePlayer in another process.
  • Presets - Bug fixes and the folowing additions
    • Fixes:
      • Update pulse not working on Presets Component
      • Delete pulse not working on Presets Component
      • Controls list container delete preset button width stretched
      • Settings/bankParSettings initial rollover error from trying to access None type - caused by not yet stored previous values.
      • Blend enabled for Presetblendtime par in parent in init when PresetsComp reinitialized after previously being initialized (these pars should be filtered so not to appear in the settings list)
    • 'Updates:
      • Pulse parameters disabled by default
      • Created internal preset values DAT inspector.
      • Added functionality for updating all presets in all banks when a parameter is added, removed or renamed on the target component. A confirm update dialog is created when a change is recognized. Also a pulse button has been added to the Setup page to manually update all presets with new or changed parameters. This is useful if a default value (other than the TD default value for the parameter type) for the new parameter for all the updated presets is wanted to be set. The workflow is as follows:
      • Added new parameter(s)
      • When confirm dialog opens and asks to update all presets, press cancel
      • Set the value of the parameter
      • Press Update All Presets button on Setup page and confirm.
      • Now all previously stored presets will have the desired value(s) set in the new parameters.

disable both recall and blend of parameters with expressions by default on store of preset with expression in parameter filter target components "presets parameters" in settings list so they are not viewable or editable.

  • Palette:probe component enhancements.
    • Cook times of nodes that haven't cooked recently are better-reported.
    • Can use mouse wheel to zoom large networks (but not go between networks yet).
  • Palette:camSchnappr bug fixes and improvements.
    • Autoblend fixed.
    • Autoblend can now be shown in preview output whereas previously the mask was not applied to this output.
    • Added additional parameters for the Autoblend feature to control the blend curve via RGB gamma/luminance based on Paul Bourke's Edge Blending article from
