Hyperion Engine

an open-source game engine that'll love you back

About the project

Hyperion started as a passion project in 2016, and is still worked on daily.

Our aim with Hyperion is to offer a high fidelity gaming experience even on low-end hardware using our in-house baking system to prepare as much of the lighting and effects as possible ahead of time.

That, and the editor shouldn't suck.

Features

  • Global illumination

    Offline lightmap baker : bake lightmaps ahead of time, so games can look good on a potato

    Screen-space : SSR, and HBAO are supported with and without baked lighting

    Ray-traced : DDGI probes and reflections on RTX / RDNA hardware

  • GPU-driven rendering

    Vulkan and DirectX 12 with clustered shading. Occlusion culling runs in compute and feeds indirect draws directly, including for GPU-simulated particles.

  • Multiplayer

    Multiplayer is built in. The engine includes a dedicated server and clients connect to it.

  • Strata for scripts

    Strata is a statically typed, compiled, LLVM-backed gameplay scripting language that recompiles live on save.

  • World streaming system

    Scenes are assigned to cells that dynamically stream content in and out of the world.

  • Physics

    Hyperion uses Jolt Physics for rigid bodies, and character controllers. Works over net.
