Unreal on Linux

Unreal on Linux

A tweet from TechCrunch today alerted me to Epic’s Unreal Engine 4.1 Update preview. There are a number of changes, but the big news is that the Unreal Engine has a native Linux (and, by extension, SteamOS) built target.

This is another huge development for the burgeoning Linux gaming community, and its great to see full-features engines support Linux and the new Steam Machines.

New Features

The update preview lists the following upcoming changes to the Unreal Engine in 4.1, coming later in April:

NEW! STEAMOS/LINUX SUPPORT

  • You can now package your games and deploy to SteamOS and Linux!
  • Note: For now, you’ll need to grab the source code to compile and test on Linux

NEW! FLYING AND ROLLING PROJECT TEMPLATES

  • There are 2 new project templates that demonstrate simple flying and rolling character movement!
  • The Flying templates (C++ and Blueprint) feature simple flying movement.
  • The Rolling templates (C++ and Blueprint) feature a physics-based rolling ball as the player character

NEW! SCENE OUTLINER FOLDER SYSTEM

  • It is now possible to organize actors in the Scene Outliner using folders
  • The create button will create you a new folder containing the currently selected actors.
  • Visibility toggling on folders affects all their contained actors.

NEW! ASSET DELETION ASSISTANT

  • This feature makes it easy to delete assets by helping you interactively inspect and repair references.
  • Allows graceful cleanup of assets still being referenced on disk or in memory
  • You can click on any referenced asset to navigate to it and fix it up manually.
  • You can Replace References, formally known as “Consolidate”.
  • You can perform a Force Delete, or you can Cancel and go handle the references yourself.
  • Allows for multiple simultaneous deletes.
  • Even if an asset is referenced by other assets, as long as they are also being deleted, it won’t flag that as a problem.
  • Double Clicking on referenced assets will open their editor
  • If an asset is being referenced in the open map, Double Clicking the map asset will take you to it in the open map.

NEW! UNDO HISTORY WINDOW

  • The Editor now has a way to access the undo history!
    Undo History Window
  • You can access the Undo History window from the Windows menu (Windows > Undo History).

NEW! JUMP TO CONNECTION IN GRAPH

    Debug Histogram Visualization

NEW! DEBUG HISTOGRAM VISUALIZATION

  • Values can be recorded and histograms can be drawn from both C++ code and Blueprints!

NEW EXPERIMENTAL FEATURE: TRANSLATION EDITOR

  • The Translation Editor makes it easier to edit translations for strings in your game code and assets.
