This node is a specialized version of the Filter by Expression node. You can use it to filter out work items that are inside or outside of a specified range. You can also choose whether the work items should be matched using their frame value, index, or a custom numeric attribute value.
If the Set Range Attribute parameter is on, then the node writes the range values to a float attribute on each work item and adds a
Determines when this node will generate work items. You should generally leave this set to “Automatic” unless you know the node requires a specific generation mode, or that the work items need to be generated dynamically.
All Upstream Items are Generated
This node will generate work items once all of the input nodes have generated their work items.
All Upstream Items are Cooked
This node will generate work items once all of the input nodes have cooked their work items.
Each Upstream Item is Cooked
This node will generate work items each time a work item in an input node is cooked.
The generation mode is selected based on the generation mode of the input nodes. If any of the input nodes are generating work items when their inputs cook, this node will be set to Each Upstream Item is Cooked. Otherwise, it will be set to All Upstream Items are Generated.
Remove Items in Filter Range
The node discards work items that fall within the Filter Range.
Keep Items in Filter Range
The node keeps work items that fall within the Filter Range.
Determines which work item attribute to compare against the Filter Range.
The node uses a work item’s frame value to determine if it is included in the range.
The node uses a work item’s index value to determine if it is included in the range.
The node uses a custom attribute, as specified by the Custom Attribute parameter, to determine if a work item is included in the range.
Specifies the name of the custom attribute the node uses to determine if a work item is included in the range. Since the Filter Range is numeric, the value of the custom attribute you specify must also be numeric (either a float or integer) for filtering to work correctly.
This parameter is only available when Filter By is set to Custom Attribute.
The start and end value for the range. These values are inclusive. For example, if the range goes from 1 to 10, a work item with a frame value of 10 will be inside the range.
Set Range Attribute
When on, the node writes the range values to a float attribute on each work item and adds a
range attribute to each work item. This attribute is useful when you're using this node to select a subset of frames from a ROP Fetch node.
Other downstream ROP Fetch nodes that are operating in batch mode will also use the
range attribute when generating batches. So if you plan to use the filtered work items with a ROP Fetch, you should enable this parameter.
This parameter is only available when Operation is set to Keep Items in Filter Range.
Include Output Files
When on, the node preserves the output file lists on the filtered work items.
