Syntax

UCLASS (MinimalAPI)  
class UMaterialGraphNode : public UMaterialGraphNode_Base

Variables

  Type Name Description
Public variable bool bIsErrorExpression Set to true if this expression causes an error in the material
Public variable bool bIsPreviewExpression Set to true if this expression is currently being previewed
Public variable bool bPreviewNeedsUpdate Set to true when Expression Preview compiles, so we can update SGraphNode
Public variable FSimpleDelegate InvalidatePreviewMaterialDelegate Called when the preview material attached to this graph node needs to be updated
Public variable FSetMaterialDirty MaterialDirtyDelegate Marks the Material Editor as dirty so that user prompted to apply change
Public variable UProperty TObjectPtr< class UMaterialExpression > MaterialExpression Material Expression this node is representing
Public variable FRealtimeStateGetter RealtimeDelegate Checks if Material Editor is in realtime mode, so we update SGraphNode every frame
