Generates work items that render an IFD file using Mantra. The IFD file can be read from upstream, or manually specified with a custom path.
$HH/help/files/pdg_examples/top_rop example shows how you can use this node to create work items that render an
.ifd file with Mantra.
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.
How the processor node handles work items that report expected file results.
If the expected result file exists on disk, the work item is marked as cooked without being scheduled. If the file does not exist, the item is scheduled as normal. If upstream work item dependencies write out new files during a cook, the cache files on work items in this node will also be marked as out of date.
Automatic (Ignore Upstream)
The same as Automatic, except upstream file writes do not invalidate cache files on work items in this node.
If the expected result file exists on disk, the work item is marked as cooked without being scheduled. Otherwise the work item is marked as failed.
Work items are always scheduled and the excepted result file is ignored, even if it exists on disk.
The source of the IFD file
Upstream Output File
Uses the output file produced by the upstream work item as the path to the IFD file.
Custom File Path
IFD file specified by a custom filepath.
The data tag used to select the result from the upstream work item.
The path to the IFD file.
Overrides the image output file name.
Extra Mantra Args
Specifies extra arguments that will be passed to the Mantra executable when rendering the IFD.
TOP Scheduler Override
This parameter overrides the TOP scheduler for this node.
Work Item Priority
This parameter determines how the current scheduler prioritizes the work items in this node.
Inherit From Upstream Item
The work items inherit their priority from their parent items. If a work item has no parent, its priority is set to 0.
The work item priority is set to the value of Priority Expression.
Node Defines Priority
This parameter specifies an expression for work item priority. The expression is evaluated for each work item in the node.
This parameter is only available when Work Item Priority is set to Custom Expression.
