anyone know what causes this? it messes with my OCD and it exists on default nodes like spawnactor?

as far as i can see it seems to be an ‘OrphanedPin’ from RewireOldNodeToNew but i cant get rid of it without a RefreshNode.

which leads to my second question, whats the c++ equivalent of RefreshNode

ive tried rebuilding, updating the graph etc but none have the same effect

At a glance in FBlueprintEditorUtils you could trigger RefreshAllNodes for your current blueprint or RefreshGraphNodes for a specific graph.

K2Node_FormatText.cpp has a refresh call where it triggers

GetGraph()->NotifyNodeChanged(this);
FBlueprintEditorUtils::MarkBlueprintAsStructurallyModified(GetBlueprint());

Perhaps that can lead you to the solution?

thanks ive tried node changed, not sure if i’ve tried the second one, will update when i do :slight_smile:

	GetGraph()->NotifyGraphChanged();
	GetGraph()->NotifyNodeChanged(this);
	FBlueprintEditorUtils::MarkBlueprintAsModified(GetBlueprint());        FBlueprintEditorUtils::MarkBlueprintAsStructurallyModified(GetBlueprint());

ive tried all of these with no success :frowning:

no dice, also the weird thing is it technically happens when you reconstruct the node.

void RefreshNode()
{
	//Remove orphaned Pins
	for (int32 PinIndex = Pins.Num() - 1; PinIndex >= 0; --PinIndex)
	{
		if (Pins[PinIndex]->bOrphanedPin == true)
		{
			RemovePin(Pins[PinIndex]);
		}
	}
	GetGraph()->NotifyNodeChanged(this);
}

lacking a good solution this works, maybe its intended by Epic to keep them but it usually only keeps the last one so feels like a bug
