Control (UI) Default Value Function
asset none The asset to assign to the LookFile.
resolveImmediately No When set to Yes, LookFileResolve runs on the root of the scene
as part of this node. This is useful for overriding or layering
scene root attributes from published LookFile assets
This option has special behavior during LookFile baking. Instead
of resolving, it appends the Look to the
lookfile.referencedAssets attribute. This gets included in the
resulting LookFile and maintains a live reference to it during
subsequent Katana standard resolution.
Flush Look File Cache N/A Click to flush the LookFile cache and force a reload.
LookFileLightAndConstraintActivator
Katana maintains a list of lights, cameras, and constraints at /root/world within the Scene Graph. When a LookFile
brings in a light or constraint, the lists at /root/world need to be updated. The LookFileLightAndConstraintActivator
node activates LookFile lights and constraints by updating the respective lists. Because it reads its input from a
LookFile-resolved scene, you should place it after either a LookFileManager or LookFileResolve node.
Choose Search Entire Incoming Scene... or Search Incoming Scene From Scene Graph Selection... from the
Action menu to find available lights and constraints.
• Entries are organized by product, location, and then light and constraint paths.
• Gray entries are pending -- found by the searching tools but not yet enabled in the scene.
• Pending entries are not saved from session to session.
• Locations (entries immediately below the product entries) may be refreshed individually by choosing Search From
Selected Locations from the right-click menu. This option is only available when one or more location entries are
selected.
To enable a pending entry, choose Enable from the right-click menu at any point within the hierarchy.
Enable and disable operations executed in this manner always act upon the selected entries and all of their children.
Individual light and constraint paths may also be enabled by clicking on the checkbox next their names.
To enable everything at once:
1. First, choose Search Entire Incoming Scene... from the Action menu.
2. When that has completed, choose Select All from the Action menu right-click on any entry and choose Enable.
