Fetch channel node

Imports channels from other OPs.

The Fetch chop imports channels from other OPs. It can grab either the regular control channels from any OP, or data channels that are output from chops. Control channels are those channels associated with parameters of any OP. Data channels are only present in chops, and are the channels output by chops.

The Fetch chop can get the output channels from chops in other chop networks.

The Channels field also supports channel groups with the syntax @channelgroupname.

Note

Fetching cannot be recursive. If a CHOP exports to an object’s channel, and that object channel is fetched, the Fetch CHOP cannot feed to the CHOP that exports. This will produce an error message in the Fetch CHOP. If this occurs, you will have to lock the Fetch CHOP before exporting back to the object.

Parameters

Source

Node	The Node and Channels determine where the channels come from. They are concatenated together, so a channels of “tx” and a path of “/obj/model” will fetch “/obj/model/tx. They also accept globbing, so a Node of /obj/* and a channel of tx would select all the tx channels from all the nodes inside
Channels	This field is appended to the specified Node to complete the path. Wildcards ( and ?) and multiple entries are allowed. t? implies all translate channels, tx, ty, tz. Alternately, you can set leave the node blank and specify the full path in Channels, such as /obj/geo/.
Fetch	If fetching from another CHOP, you can fetch its OP Control Channels or CHOP Data Channels. All other OPs have only Control Channels, so leave this menu set at “OP Control Channels”.
Select	Fetched channels can be eliminated to include only control channels that have been added, or further, channels that have been added and are animating over the start/end time range. Applies to OP Control Channels.

Channel

Channel Names

Sets how the fetched channels are named. A : is placed in the channel name where / is in the path.

Channel Name	Only use the name of the channel.
OP and Channel Names	Include the parent OP name with the channel name, separated by a colon (:).
Full Path Name	Use the full path as the name, with the parts separated by a colon (:).

Channel Range

Indicates how much of the channel to fetch.

Use Full Animation Range	All of the animated range.
Use Current Frame	Only the sample at the current frame.
Use Start/End	Specify the range below.

Start

The beginning of the fetch.

End

The end of the fetch.

Sampling Method

Determines the sample rate to be used.

New Rate (Same Index Range)	Resample to new rate below.
Resample From Maximum Rate	Use the highest rate found.
Resample From Minimum Rate	Use the lowest rate found.

Sample Rate

The sample to use if “New Rate” is selected, or if no rates are found.
