Replace CHOP

Summary

The Replace CHOP can be used to replace channels very quickly. The output of channels in Input1 will be replaced by channels found in Input2 if a matching channel exists in Input2. Any channels that are in Input1 and not in Input2 will be output without being replaced.

You can also use this to quickly delete channels (this method can be faster than the Delete CHOP). To do this send all the channels to Input2, then send the channels you want to keep to Input1.

Parameters - Replace Page

Length length - - Determines the start/end range of the output.

  • First Input first - Uses the range of Input1.
  • Second Input second - Uses the range of Input2.

Notify on Change notify - A performance diagnostic that notifies the user when the input names change.


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).
