In their own words
Armory3D
Armory3D is a free, open-source 3D game engine that works as a Blender add-on and external SDK. It targets games for Windows, Linux, macOS, iOS, Android and the web, with visual scripting and Haxe available for game logic. Its scriptable renderer supports deferred and forward paths, and developers can create custom render paths. The engine includes a UI library and editor, physics based on Bullet for rigid and soft body simulation, and an option to use Oimo. Navigation meshes support real-time pathing for objects marked as actors. Effects and animation include emitter and hair particles with GPU instancing, GPU skinning, bones, keyframes, shape keys and tilesheets. Listed lighting features include voxel-based ambient occlusion, lightmapping, area lights, reflection probes and IES textures. The setup guide asks users to install Blender 4.5.x LTS and says Blender 3.3 LTS and earlier are unsupported. The repository identifies the license as zlib/libpng and permits commercial use subject to its stated restrictions. The privacy policy says Armory software does not collect, market or sell user data.
Flax Engine
Flax Engine is a 3D game engine written in C++ and C#, with visual scripting and full Editor source code available. It supports C++, C#, and visual scripting, with hot-reloading for both programming languages in the Editor. Rendering features include real-time global illumination, reflections using custom software ray tracing, and GPU lightmap baking. World-building tools cover terrain, foliage, fog, nested prefabs, level streaming, and large-world 64-bit coordinates. Multiplayer projects can use low- and high-level networking APIs. Its Online system supports services such as Steam, Xbox Live, and PlayStation Network for profiles, friends, achievements, presence, and cloud saves. Supported targets include Windows, Linux, Android, iOS, macOS, web, PlayStation 4 and 5, Xbox One and Series, and Nintendo Switch. Web support is experimental and lacks C# scripting, video playback, and some other engine features. NDA-protected platform support is excluded from the public repository. The engine is free for non-commercial or educational use; commercial releases pay a 4% royalty on earnings exceeding $250,000 per calendar quarter.
