The primary means of loading external assets (models, animation and cameras etc) from caches into Gaffer. Gaffer’s native file format is the .scc (SceneCache) format provided by Cortex, but Alembic and USD files are also supported. Other formats may be added 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.


The output scene.


The on/off state of the node. When it is off, the node outputs an empty scene.


The name of the file to be loaded. The file can be in any of the formats supported by Cortex’s SceneInterfaces.

Supported file extensions : abc, lscc, scc, usd, usda, usdc, usdz, vdb


May be incremented to force a reload if the file has changed on disk - otherwise old contents may still be loaded via Gaffer’s cache.


Limits the parts of the scene loaded to only those with a specific set of tags.


The transform used to position the cache. This is applied to all children of the cache root.
