When this toggle is enabled, attributes are copied from the source items only after the work items are cooked. This is useful when copying output files producing during the cook, for example.

When this toggle is enabled, the attributes from all work items on the second input will be copied onto each of the work items on the first input. No Match By condition is used to filter the work items.

Whether to match by index value (roughly, match by position) or by an attribute.

When Match by is “Attribute”, the name of the attribute to use to match up work items (items in the second input will match items in the first input that have the same value of this attribute).

When Match by is “Attribute”, the type of the attribute to match (Integer, Float, or String).

When this is on, items from the first input are only passed down to the output if they matched. Items that didn’t match an item in the second input are filtered out. (Items are never passed down from the second input.)

A space-separated list of names/patterns describing which attributes to copy from items in the second input onto items in the first input. The default is * (copy all attributes).

For example, you could set this to foo bar baz to only copy those three attributes, or file_* to only copy attributes whose names start with file_. See the Attribute Pattern Syntax documentation for more details.

When this is on, also copy output filenames onto the items in the first input.
