UCLASS (MinimalAPI, BlueprintType)  
class UAvaMaterialParameterModifier : public UAvaArrangeBaseModifier

This modifier sets specified dynamic materials parameters on an actor and its children

Type	Name	Description
bool	bShowMaterialParameters	Used by child classes to override MaterialParameters
bool	bUpdateChildren	Will also look into attached children actors
TSubclassOf< UMaterialInstanceDynamic >	MaterialClass	Filter material type for child modifiers
FAvaMaterialParameterMap	MaterialParameters	Which parameters should we set on the Material Designer Instance
TMap< TWeakObjectPtr< UMaterialInstanceDynamic >, FAvaMaterialParameterMap >	SavedMaterialParameters	Used to restore Material Designer Instance parameters to their original state
