After three years of sustained R&D investment and a team of more than 15 engineers, CORYS has been officially certified as an Unreal Engine Service Partner by Epic Games — joining a very small circle of European industrial companies to hold this status.
Three Years of Deep Technical Investment
Since early 2023, CORYS’s R&D team has undertaken a comprehensive overhaul of its image generation system and associated production tools, migrating to Unreal Engine. This work — carried out by a dedicated team of more than 15 people — spanned 3D modelling, the asset production pipeline, real-time integration into simulators, and the development of proprietary internal tools tailored to the requirements of the nuclear and railway sectors.
The project unfolded in successive phases: an initial period of technology acquisition and team training, followed by the integration of Unreal Engine into CORYS’s simulation platform, and then the development of a 3D database production tool. From early 2025, this foundational work translated into deployment on the first two pilot simulators — delivering ultra-large-scale open world environments at 5 cm precision, handling millions of objects in real-time.
“This isn’t just a certification. It’s validation that the technical path we chose — betting on Unreal Engine as the foundation for next-generation professional simulation — was the right one. We’re not just users of the technology. We’re now part of the global network shaping where it goes next.”

What the Certification Means in Practice
The Unreal Engine Service Partner designation delivers concrete value across four dimensions:
- For our simulators and clients — Migration to Unreal Engine achieves an unprecedented level of visual realism. The fidelity of simulated environments — lighting quality, rendering fluidity — directly enhances training effectiveness: the closer the simulation is to the real environment, the more effectively operators develop transferable reflexes.
- For production efficiency — Unreal Engine provides a modern, collaborative, and high-performance visual content creation pipeline. The overhaul of our production tools reduces development cycles, simplifies updates to 3D assets, and improves our responsiveness to changes in simulated installations.
- For our industrial positioning — Service Partner status grants privileged technical support from Epic Games, access to advanced resources, and positions CORYS as a reference integrator of this technology — the only certified entity within the FRAMATOME / EDF group. CORYS is also now officially listed in the global UE Service Partner Directory.
- For the Group — The Flamanville EPR fuel loading machine simulator already integrates Unreal Engine for camera view simulation. As simulation plays an ever greater role in operational competency maintenance — particularly for EDF’s nuclear fleet and new reactor programmes — this certification ensures the Group has an in-house provider capable of meeting all Unreal Engine development needs.
Open for External Challenges
Beyond the certification itself, CORYS is announcing that its R&D team is now actively open to external collaborations. Whether through co-development projects, technical consulting engagements, or Unreal Engine content production, the team is ready to bring its expertise to partner organisations.
This move signals a broader ambition: not just to build exceptional simulators for CORYS clients, but to actively contribute to the professional simulation ecosystem at large.
