Syntax
class UMovieSceneMaterialParameterSystem : public UMovieSceneEntitySystem
Remarks
System responsible for tracking and animating material parameter entities. Operates on the following component types from FMovieSceneTracksComponentTypes:
Instantiation: Tracks any BoundMaterial with a ScalarParameterName, ColorParameterName or VectorParameterName. Manages adding BlendChannelInputs and Outputs where multiple entities animate the same parameter on the same bound material. BoundMaterials may be a UMaterialInstanceDynamic, or a UMaterialParameterCollectionInstance.
Evaluation: Visits any BoundMaterial with the supported parameter names and either a BlendChannelOutput component or no BlendChannelInput, and applies the resulting parameter to the bound material instance.
