The people behind the Tales of Nalstone youtube channel are using UE4 for creating a short film (or films). They occasionally do livestreams on youtube - showing their workflow and process of creating assets (3D modeling, texture creation, etc.) and working in UE4.
It’s pretty interesting to watch, and they usually give out some good general advice throughout the stream to the people in the chat. In a way, it’s sort of motivational, because you get to watch someone else create 3D content in realtime and observe their workflow. Puts things in perspective after having seen a lot of sped up and edited production videos, and such.
