Fetch CHOP

Summary

The Fetch CHOP imports parameters from all OP types, like SOPs, CHOPs and objects. Control channels are those channels associated with parameters of any OP.

Select the OP using menus, or by entering the path in the Channels field.

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.

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

Parameters - Source Page

OP - The OP and Channels parameters determine where to obtain the channels.

Specifying Groups - You can specify groups in the Channels field using the @ symbol before the group name. For example: /obj/@groupname. You can also specify a "NOT" selection with an ^. For example /obj/^@groupname will select all channels aside from the specified group.

Channels - The list of parameters names (which can include wildcards) you want to get from the OP(s).

Select - Fetched channels can be eliminated to include only control channels that have been created, or further, channels that have been created and are animating over the start/end time range. This menu applies to OP Control Channels only.

• All Channels - All channels that match the OP and Channels path are included.
• Created Channels - Only channels that have been created and appear in the channel list for the OP) are included.
• Non-Constant Channels - Only created channels that are animating over the start/end range are included.

Parameters - Channel Page

Channel Names - Sets how the fetched channels are named. A colon ( : ) 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 colons ( : ).

Channel Range - Indicates how much of the channel to fetch:

• Use Full Animation Range - All of the animated range. If any of the specified channels are animating, there will be samples for each frame of the animation. Otherwise, if all the specified channels are constant, the CHOP length will be just one sample long.
• Use Current Frame - Only the sample at the current frame.
• Use Start/End - Specify the range below.

Start / End - Specify the beginning/end sub-section of the fetch. Units are set in the CHOP Common Page.

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.
