Epic's next big engine update is all about Linux.
Epic Games will push out a major update for Unreal Engine 4 later this month. UE 4.1 will, among other improvements, bring SteamOS and Linux support to the engine.
"Folks have been asking about our early Linux efforts and support for Valve's SteamOS and Steam Machines," said Technical Director Mike Fricker in an Unreal Engine blog post. "We have good news for you! The 4.1 source code has initial support for running and packaging games for Linux and SteamOS. We love Linux!"
Updates, including more fleshed out support for Linux and SteamOS, will be hitting on a regular (hopefully monthly) basis, thanks to the new UE4 subscription plan.
The other big news coming from the UE4 update: The "Elemental" demo that first appeared in 2012 will now be made available to Unreal Engine 4 users. Assets, etc. from the demo can now be used in whatever your project might be.
Other additions include "Flying and Rolling Project Templates," Scene Outliner Folder System, Asset Deletion Assistant, Undo History Window, and a host of other improvements, additions, and fixes (check out the blog post for a full list).
