CPlusPlus CHOP


The CPlusPlus CHOP allows you to make custom CHOP operators by writing your own plugin using C++.

See Write a CPlusPlus Plugin and the other articles in the C++ Category for more detailed information on how to make plugins for use with this node and how to access example projects.


Parameters - Load Page

Plugin Path plugin - The path to the plugin you want to load.

Re-Init Class reinit - When this parameter is On, it will delete the instance of the class created by the plugin, and create a new one.

Re-Init Class reinitpulse - Instantly reinitialize the class.

Unload Plugin unloadplugin - When this parameter goes above 1, it will delete the instance of the class created by the plugin and unload the plugin. If multiple CHOPs have loaded the same plugin, they will all need to unload it to release the file.

Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
