What’s Overload?
Overload is a free, open-source 3D game engine made in C++ with Lua as its scripting language.
Originally created in 2019 by Benjamin VIRANIN, Max BRUN, and Adrien GIVRY as a graduation project, it has since evolved into an community-driven initiative supported by dozens of contributors.
Overload pillars are:
- 🐣 Ease of use – Inspired by other commercial engines, so you feel right at home.
- 🧊 Simplicity – Minimalistic by design, avoiding unnecessary complexity.
- 💭 Pragmatic Design – Features are carefully considered and deeply integrated.
- 📄 Documentation – Scripting API and documented source-code.
- 🤝 Community-Driven – Welcoming contributions and feedback from all developers.
- ⚙️ Modern C++20 – Leveraging the power and safety of up-to-date C++ features.

Building From Sources
Windows (MSVC)
git clone https://github.com/Overload-Technologies/Overload
cd Overload
.\gen_proj.bat vs2022 # generate project files for Visual Studio 2022
.\Overload.sln # Open the solution in Visual Studio
[!note]
Officially supported actions for gen_proj.bat are: vs2022 (default), gmake, codelite.
Refer to premake’s website for more information.
Linux (Clang)
git clone https://github.com/Overload-Technologies/Overload
cd Overload
./gen_proj.sh gmake # generate project files for Makefile
make -j$(nproc) # build the project using all available CPU cores
The editor requires zenity to be installed on Linux.
[!note]
Officially supported actions for gen_proj.sh are: gmake (default), codelite.
Refer to premake’s website for more information.
Architecture
Overload is divided into 11 modules: 9 libraries (SDK), and 2 executables (Applications).
Overload SDK
The Overload SDK is the core of the engine. It is a set of libraries used by our applications: OvGame and OvEditor.
We designed theses libraries with reusability in mind. They are highly modular and easy to extract from a game engine context.
OvDebug: Logging and assertions.OvTools: Serialization, file system, platform, events, clock, and more.OvMaths: Vectors, matrices, quaternions, transforms.OvAudio: Audio engine, built around SoLoud.OvPhysics: Physics engine, built around Bullet3.OvRendering: Rendering engine, built around BareGL.OvWindowing: Handles inputs and windows using GLFW.OvUI: Widget-based UI, leveraging ImGui under the hood.OvCore: Component-based scene system, scripting, and resource management.
Overload Applications
Overload applications use the Overload SDK to operate.
OvGame: A data-driven executable for any game built with Overload.OvEditor: An editor for building your game.
Dependencies
Overload depends on a few third-party libraries:
