Summary
[edit]

The Parameter CHOP gets parameter values, including custom parameters, from all OP types.

(This replaces the Fetch CHOP.)

Retrieve from parameters alternatively using a node.par.Customname expression of the Par Class, or the Parameter Execute DAT.

See the Select CHOP for retrieving channels from the output of other CHOPs.

Parameters - Source Page

Operators ops - The operators determine where to obtain the channels. Specify or more operator names or paths. Examples: wave1, slider*, constant[1-9] constant[10-19:2], ../base1. Or select the operators using the menu.

Parameter parameter - The list of parameters names (which can include wildcards) you want to get from the OP(s). One or more parameter, or * for all parameters. You can also specify a "NOT" selection with an ^. Or select the parameter using the menu. See Pattern Matching.

Name Format nameformat - - Channels can be named suitably for multi-exporting. See CHOP_Export.

  • Parameter Name parameter -
  • OP and Parameter Names op -
  • Full Path Name path -

Rename from renamefrom - See Pattern Matching.

Rename to renameto - See Pattern Replacement.

Custom custom - Output the operators' custom parameters.

Built-In builtin - Output the operators' built-in parameters.


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).
