What Are the Best Game Engines?
Lumberyard is a free, cross-platform engine. But recently, Amazon has taken its game engine and transformed it into an open-source model. Open3D is the latest from Amazon. It builds on top of Lumberyard and creates a more modular approach to game development.

  • Unreal Engine change its price for non-game apps
    O3DE[0] looks interesting - owned by the Linux Foundation, originally based on Amazon's Lumberyard, and it has some big players involved: Amazon, Epic Games(!), Microsoft, NVIDIA, Intel, Huawei, Red Hat, [0] https://o3de.org. - Source: Hacker News / almost 3 years ago
  • Alternative Game Engines for Marooned Unity Developers
    03DE: Open source game engine, under Apache License 2.0, developed by Amazon and the linux foundation. Seems to work under a modular package called "gems", that you can use to pull in the functionality you need. It uses c++ as it's main language, but you can use Lua, python or visual scripting for scripting stuff. Has multiplayer built into the engine and what they call a "robust" system for open-world games.... Source: almost 3 years ago
  • Someone dropped the source code for Far Cry 1 on archive.org
    Note that Lumberyard became "Open 3D Engine" (yes, very inspired name) which is Apache 2 licensed: https://o3de.org/ https://github.com/o3de/o3de/ AFAIK all development in Lumberyard has ceased and moved to O3DE. - Source: Hacker News / about 3 years ago
  • Did they take down the post about motion matching recently?
    Many pages in o3de.org are down. They are working on it. Source: about 3 years ago
  • Is SPIRV-Cross a valid option to target Metal from HSSL?
    I've worked on this a bit as part of the shader pipeline of Open3DEngine, From my experience there are very few compatibility issues between hlsl and sprir-v, sprir-v to msl however does run into a few issues.Here are the ones I remember. Source: over 3 years ago
