The real-time voxel game engine powered by path tracing.

Create the game of your dreams in highly detailed and dynamic worlds using the embedded editor and C/C++ or Lua.

IOLITE Feature Highlights

Screenshot of IOLITE v0.4 which is currently in beta. The forest sample scene has been created solely using the editor and the new voxel editing plugin. The characters were created using MagicaVoxel and can be directly used as assets.

Highly specialized for dealing with large, highly detailed, and dynamic voxel worlds, made possible by modern desktop-level CPUs and GPUs
Features fully dynamic real-time global illumination using a mixture of path tracing and screen space techniques; no ray tracing capable GPU required
Implement your game using C/C++ or Lua; you can even create a custom scripting backend for the language of your choice
IOLITE comes with a fully-featured editor for creating game worlds. Use our open-source plugins to extend the functionality, like, e.g., authoring voxel assets directly in the editor
Extend the engine and editor functionality using the plugin system in conjunction with the native C/C++ API
Highly flexible and thus not exclusively tied to creating games. Use IOLITE as a complete game creation package, solely as a renderer, for creating a procedural voxel editor, and more. The possibilities are endless
Features subsystems for sound, particles, destruction, post-processing, and more right out of the box

Download IOLITE for Free

Go ahead and give IOLITE's most recent public pre-release build a spin. If you've got a question or run into an issue, don't hesitate to ask on our Discord server. Please also make sure to give our permissive license a read.

Samples and More

Flatpak Repository

In addition to the pre-packaged builds, IOLITE is available via our Flatpak repository. Flatpak builds provide automatic updates and also work on more uncommon Linux distributions. To add our repository as a remote, install IOLITE, and launch it, please perform the following steps:

$ flatpak --user --no-gpg-verify remote-add md https://media.missing-deadlines.com/iolite/flatpak
$ flatpak --user install md com.missing_deadlines.IOLITE
$ flatpak run com.missing_deadlines.IOLITE
$ # All data is stored in ~/.var/app/com.missing_deadlines.IOLITE/data/

Installing also adds a shortcut to IOLITE to your favorite launcher. After that, you can update IOLITE like any other Flatpak application:

$ flatpak --user update com.missing_deadlines.IOLITE

In contrast to the portable builds, the Flatpak builds are also shipped with all the latest samples from the GitHub repository.

Support the Development with IOLITE PRO

IOLITE PRO is an extended version of IOLITE available for everyone who wants to support the development of this project.

In addition to the features of the free version, IOLITE PRO provides, for example, the C/C++ API for writing native plugins, a mesh voxelizer, and the option to disable the splash screen. Click the button below if you want to learn more.
