Create a Night-Moon scene in 3 minutes (no 3rd party softwares)

Hello guys,
I noticed that many online tutorials on the forums,youtube etc… are using a lot of 3rd-party tools in addition to unreal engine ( they use 3DS-MAX,Blender…etc); I admit that it won’t cause any harm but why would we use indirect methodologies while UE4 offers us all the necessary assets to fulfill the task?
In this** 3 minutes** tutorial I explained how to make a night scene that includes a moon using ue4 purely.

Thank you for your attention, bye bye !
