Amazon Lumberyard free AAA Game Engine.
Amazon Lumberyard is the free game engine that gives you a combination of feature-rich development technology, native integration to the AWS Cloud to make it easier to create live and multiplayer games.
The visuals technology of Lumberyard is based upon CryEngine, which has created award-winning graphical performance, with support for iOS Metal to bring this level of performance also to mobile devices.
You get powerful rendering technology and authoring tools to create near-photorealistic 3D environments and stunning real-time effects, including physically based shaders, dynamic global illumination, a particle effects editor, vegetation tools, real-time dynamic water caustics, volumetric fog, and filmic features such as color grading, motion blur, depth of field, HDR lens flares, and much more.
Real-time gameplay editing enables you to iterate on gameplay and immediately see your results, without waiting for builds or leaving the editor. Yo can import game objects, fine tune their behavior, and in one keystroke, instantly play the game you just created.
Additionally, Lumberyard’s asynchronous asset processor automatically converts and optimizes game assets for your device platforms while you work.
The Twitch JoinIn feature within Lumberyard lets you build multiplayer games that allow Twitch broadcasters to instantly invite fans to join them side-by-side in the game. Once invited, a fan can jump into the broadcaster’s game with a single click in the Twitch chat channel, while others continue to watch.
