I’m not sure if it has a specific effect on lightmass which is why it was designed like that, but here’s the code:

void ALightmassPortal::PostEditMove(bool bFinished)
{
	Super::PostEditMove(bFinished);

	PortalComponent->RelativeScale3D.X = 10;
	PortalComponent->MarkRenderStateDirty();
}

It’s in PortalComponent.cpp around line 60 in 4.16.1. Just comment out the ->RelativeScale3D.X line and recompile. Haven’t tested to see if it makes a difference in lightmass or not yet.
