Simulation

Create simulations that feel (almost) like real life.

Prepare for the unexpected. Prevent life-threatening situations. And do it with a level of accuracy and realism that make it hard to believe it’s a simulation at all. With the real-time rendering power of Unreal Engine, simulation teams no longer have to compromise.

Updated game templates for Unreal Engine 5.6—available now

We’ve slashed template sizes to speed up downloads and pack in more features. Plus, meet Variants, a new way to tailor templates for your specific gameplay style, whether it’s a side-scrolling platformer, open-world racer, or top-down strategy game.

Features for simulation

With Unreal Engine, everything’s included out of the box: modeling, animation, and effects tools are built right in. And when you want to go beyond the box, there’s access to the complete source code, a robust C++ API, and intuitive Blueprint visual scripting for non-programmers.

Data handling that scales

With native support for many industry-standard 3D asset formats, virtual terrains, and communication protocols, and the ability to convert entire scenes at high fidelity through Datasmith, getting your data into UE5 is easy. Looking to build big? Nanite enables you to render massive amounts of geometric detail, while World Partition means you can easily manage and stream your levels.

Critical fidelity

When realism is essential to the success of your project, look no further than UE5: with features like real-time ray tracing and dynamic global illumination, interactive applications have never been more convincing. Plus, with built-in particle and physics systems, you can create film-quality real-time effects and simulations for everything from fire, smoke, and water, to cloth, destruction, and vehicles.

Multi-platform deployment

From a single UE5 project, you can deploy your simulation to anything from mobile devices and touchscreens to VR headsets and MR holograms. Deliver high-performance interactivity to any device with a web browser via Pixel Streaming, display real-time content at ultra-high resolution across multiple screens using nDisplay, or create a networked application for multiple participants—the choice is yours.
