Best Unity alternatives for game development
Now, if you're looking for an engine that focuses on 3D, Open 3D Engine is a stellar choice (even if it is a bit finicky). You will notice that Open 3D Engine is essentially the successor to Amazon Lumberyard (however, Open 3D Engine is managed by the Linux Foundation).

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
