0.4.3 hotfix 8 brings reversed-Z rendering, isolated camera settings, repaired skies and shadows, and fixes for Hub window flashes and startup focus. See the changelog.

What is Infernux?

Infernux is a game engine where Python is where you work and C++ is where it runs. You write gameplay, editor tools, render pipelines and numerical code in Python; a C++ runtime, a Vulkan renderer and Jolt physics do the heavy lifting. The same project ships to Windows, Linux, Android and the browser.

It is also built toward a specific goal: 3N, a Neural Network-Native engine. In most engines, AI is a plugin bolted on after the game is finished. In a 3N engine the world is data a model can read, the simulation is a place where it can act, and the shipped game is somewhere it can run.

import infernux as inx


class Spin(inx.InxComponent):
    speed: float = inx.serialized_field(default=90.0, range=(0.0, 360.0))

    def update(self, delta_time: float) -> None:
        self.transform.rotate(inx.Vector3(0.0, self.speed * delta_time, 0.0))

_{An ordinary Python class. speed appears in the Inspector and can be tuned while the game runs.}

[!WARNING] Infernux is alpha software under active development. APIs still change between releases, and the neural-network features below are roadmap items rather than shipped features. It is ready for experiments, tools and small games, not yet for a production schedule.

Highlights

• Python first. Components with Inspector fields, coroutines and prefabs. Project scripts and plugins hot-reload transactionally, including the behaviour of instances that already exist.
• A renderer you can author. Describe a RenderStack in Python and the native RenderGraph runs it: Forward, Forward+ and Deferred paths, PBR, shadows, post-processing, GPU particle graphs, skinned animation, screen and world-space UI.
• A complete game loop. Multi-scene editing, FBX and Blender import with live source sync, Jolt rigid bodies and scene queries, audio, animation state machines and Timeline.
• Compute in the game. Batch NumPy access to world data, CPU/GPU JIT and Taichi integration for numerical gameplay. This is the data path models will use.
• An editor you can extend. Dockable panels and menus written in Python. InxPackage plugins carry components, tools, assets and platform exporters. An optional MCP plugin lets agents drive the editor through the same command and undo paths you use.
• Built to be inspected. Assets keep a GUID identity from import to cooked Player. Players load a packed asset index, never your project folder.

Platforms

Requirements and known limits per platform are in SUPPORT.md.

Get started

Use the engine. Install InfernuxHub, pick an engine version and create a project. The Hub manages Python environments and Android tools for you; no native compiler is needed. Then follow the five-step start to a component spinning a cube, and continue with the courses.

Build from source. Windows needs a Visual Studio installation with the Desktop C++ workload, CMake 3.25+, the Vulkan SDK and Python 3.13. The Windows preset lets CMake select the newest compatible Visual Studio generator installed on the machine.

git clone --recurse-submodules https://github.com/ChenlizheMe/Infernux.git
cd Infernux
./scripts/setup/configure_development.ps1
conda activate infernux
cmake --preset windows-msvc-release
cmake --build --preset windows-msvc-release
cmake --build --preset windows-msvc-install-wheel
python packaging/launcher.py

If configuration cannot create the selected generator, install a CMake version that lists a compatible Visual Studio generator in cmake --help, or set CMAKE_GENERATOR to one of the listed generators and configure again.

On Linux, run scripts/setup/install_linux_dependencies.sh and bash scripts/setup/configure_development.sh, activate infernux, then use the linux-clang-release and linux-clang-install-wheel presets. CONTRIBUTING.md covers the full workflow.
