Writes scenes to cache files on disk. Gaffer’s native file format is the .scc (SceneCache) format provided by Cortex, but other formats may be supported by registering a new implementation of Cortex’s abstract SceneInterface.
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
Input connections to upstream nodes which must be executed before this node.
Input connections to nodes which must be executed after this node, but which don’t need to be executed before downstream nodes.
Output connections to downstream nodes which must not be executed until after this node.
Container for custom plugs which dispatchers use to control their behaviour.
Maximum number of frames to batch together when dispatching tasks.
If the node requires sequence execution
batchSize will be ignored.
Causes this node to be executed immediately upon dispatch, rather than have its execution be scheduled normally by the dispatcher. For instance, when using the LocalDispatcher, the node will be executed immediately in the dispatching process and not in a background process as usual.
When a node is made immediate, all upstream nodes are automatically considered to be immediate too, regardless of their settings.
The scene to be written.
The name of the file to be written. Note that unlike image sequences, many scene formats write animation into a single file, so using # characters to specify a frame number is generally not necessary.
Supported file extensions : abc, lscc, scc, usd, usda, usdc
A direct pass-through of the input scene.
