Switch CHOP


The Switch CHOP allows you to control the flow of channels through a CHOPnet. It selects one of the input CHOPs by index and copies it exactly. This is useful for selecting one of several "gestures" or actions. Only one input chop can be selected at a time.

Inputs are indexed starting at 0, so that the first input is 0, the second is 1, and so on.

If the First Input Is Index parameter is enabled, the first input is used as the "switch" and the remaining inputs will be selection choices. In this case, the second input will be indexed as 0, the third as 1, the fourth as 2, and so on (the Switch input chop is not indexed). The index value is determined by evaluating the first channel in the first input at the current frame. Only integer indices are used; fractional indices will be rounded down to the closest integer.

If the index is less than 0, then the index will be interpreted to be 0. If the index is greater than the number of input chops, the last input chop is selected.

If you wish to blend between inputs use the Cross CHOP or the Blend CHOP.


Parameters - Switch Page

First Input is Index indexfirst - If enabled, it will use the first input CHOP's first channel to determine which input to select.

Index index - The input index to use if First Input Is Index is off.

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).
