Variables

Public

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