UMovieGraphNode

This is a base class for all nodes that can exist in the [UMovieGraphConfig](API\Plugins\MovieRenderPipelineCore\UMovieGraphConfig) network.

API > API/Plugins > API/Plugins/MovieRenderPipelineCore

This is a base class for all nodes that can exist in the UMovieGraphConfig network. In the editor, each node in the network will have an editor-only representation too which contains data about it's visual position in the graph, comments, etc.
