When creating the updated version of The Elder Scrolls 4, it was necessary to interact with different engines.
Recently, the head of Virtuos studio, known to many for The Elder Scrolls 4 Oblivion Remastered, spoke with IGN and talked about working on the project.
Gilles Langourieux recalled how they managed to get this project:
«We managed to convince Todd Howard and his team that we could handle it. He had known us for some time [...] You prove what you are capable of at the pilot stage. You release a convincing vertical slice or pilot version. You agree with the Bethesda team on what level of quality or detail they think is necessary to reach the target audience, and continue working until the final version».
The TES 4 Oblivion remaster is based not only on the modern Unreal Engine 5, but also on the old one.
The developers needed to modernize the game, but at the same time Bethesda wanted the remaster to retain a piece of the "old charm":
«We realized that one of the solutions would be to combine the original engine with the new one. Virtuos, by the way, has extensive experience with Unreal. We have implemented several similar projects where we combined [engines] — this is called "engine pairing" — two engines worked together, so the gameplay was on the original engine, and rendering and new modern features were on the new one. We had to apply our experience with Unreal».
Hundreds of employees were involved in the work, with about 400 people working on the TES 4 Oblivion remaster at its peak.
