Project Titan: Unreal Engine’s 3D World Built by Thousands

Epic Games’ Project Titan kicked off in March 2024, with over 4,000 artists crafting a 3D open world in Unreal Engine 5 over 10 weeks. Released December 2024, this 64 km² landscape—nine unique biomes from deserts to cyber-cities—shows off 3D design at its rawest, built entirely in-engine.

This landscape is a testament to what’s possible when thousands of creators come together in Unreal Engine.

3D Design Core

Using Unreal’s Nanite for detailed geometry, Lumen for dynamic lighting, and Procedural Content Generation, artists modeled everything—terrain, props, characters—into a seamless 3D playground. With 10,000+ meshes, it’s a testament to Unreal as a 3D creation hub.

The Big Picture

Dropped free on Fab, Project Titan’s a hit—X users call it “insane” and a “learning goldmine.” It’s not just a demo; it’s a fully 3D-designed world that proves collaborative 3D art can redefine what’s possible.
