unreal.MovieGraphModifierNode

class unreal.MovieGraphModifierNode(outer: Object | None = None, name: Name | str = 'None')

Bases: MovieGraphSettingNode

A collection node specifies an interface for doing dynamic scene queries for actors in the world. Collections work in tandem with UMovieGraphModifiers to select which actors the modifiers should be run on.

C++ Source:

  • Plugin: MovieRenderPipeline

  • dynamic_properties (InstancedPropertyBag): [Read-Write] Properties which can be dynamically declared on the node (vs. native properties which are always present).

  • modifier_name (str): [Read-Write] The name of this modifier.
