Tuvalu: A UE5 Digital Twin of a Nation

What happened

With sea levels rising, Tuvalu faces the first case for digital statehood. Accenture worked with the Government of Tuvalu to build a photorealistic Unreal Engine 5 digital twin of a Tuvaluan islet, so the nation can preserve its heritage, governance and identity beyond the physical island.

Why it worked

• The purpose (preservation) was clear, so fidelity choices followed from it.
• Photorealism in UE5 made the twin meaningful to people, not just accurate as data.
• Scope was one islet, a size that can be captured and finished properly.

What we'd take into a client project

• Write down what the twin is for (training, monitoring, sales, preservation) before choosing capture methods.
• Start with a bounded area and a capture accuracy target, then scale.
• Plan how the twin will be updated after launch; a twin that is never refreshed becomes a static model.
