KatanaWriter

The KatanaWriter node determines the point in a node tree when a composited image from Nuke is returned to Katana over the Nuke Bridge.

Note: This node is not available by default and must be imported from an installation of Katana 4.5v1, or later, using the NUKE_PATH environment variable.
See Katana <> Nuke Roundtrips with Nuke Bridge for more information.
