Epic Games Releases June 2011 Unreal Development Kit Beta

글쓴이 Unreal Engine

Epic Games, Inc. has released the June 2011 UDK Beta, the latest version of the Unreal Development Kit (UDK), the free edition of Unreal Engine 3 that provides access to the award-winning toolset used in blockbuster video games, 3D visualizations, digital films and more.

Epic is committed to providing the UDK community with regular software releases at no charge, and the latest beta is available now at http://www.udk.com/download.

This month, we’d like to bring your attention to the Hawken UDK showcase. Hawken is a multiplayer mech combat game that is receiving early praise for its aesthetic style and ground-stomping gameplay. Adhesive Games Art Director Khang Le says that with UDK “you get a console-ready engine that has been proven with bestselling released games. Within a month of starting Hawken, we were able to test out a prototype.” Read more here.

 Hawken.

Have something cool to show us? UDK projects can be promoted to the community in the Works in Progress forum and the Released Projects forum.

It’s easy to sign up as a commercial UDK developer online. Have questions? Check out our FAQ.

June 2011 UDK Beta Upgrade Notes

New Foliage Editor

  • Quickly paint instanced foliage and decoration using the new foliage system.

 

  • Meshes and settings to be used by the foliage painting tool can be set up in the foliage editor, which is enabled through the Foliage Mode button in the toolbox.

  • Foliage instance types can specify a landscape layer name for weighting. If you set this, foliage panted on landscape will have its density modulated by the weight of the specified layer.

  • Foliage painting can now be used for altitude-based painting as well.

Map Templates

  • New map templates let you immediately configure lighting for day, night, dawn or sunset.

  • Simply drag the appropriate thumbnail from the Unreal Content Browser into a level to populate settings and achieve the desired lighting effect.

  • Map templates are fully customizable, too!

 

Mobile Workflow and Lighting Improvements

  • Lighting is now easier to implement for PC and mobile games.
    • Dominant lights are now baked into light maps for mobile.
    • Light shafts can now be activated on light mapped lights.
    • Gamma correction for mobile is now supported, providing the ability to have a consistent look across platforms.
  • This is a forward-looking feature and currently only has acceptable performance on iPad 2.

 The scene above has gamma correction enabled.

  • UDK now ships with one single editor and game content tree for both PC games and mobile games!
    • Share gameplay logic and assets between PC and mobile more easily.
    • New in-editor mobile preview mode: Preview your PC level with mobile features instantly with a simple tool bar toggle.

 

  • Mobile Previewer now has presets for iPad 2. This is a new option in the drop-down menu.

  • There is a new ‘Always Optimize Content for Mobile’ editor preference, which forces PVRTC compression and flattening, providing high-quality textures when previewing on mobile devices.

  • A guide to migrating mobile projects from previous versions of UDK to the June UDK Beta is available now as well.

Simplygon Static Mesh Reduction

  • Simplygon is used to automatically generate game-ready Level of Detail models (LODs) for a specific pixel resolution.
    • Simplygon uses a proprietary mesh reduction method that retains geometrical LOD integrity and visual quality of LOD switching, producing AutoLODs that can directly be used inside triple-A games.
    • Unreal Engine 3 leverages Simplygon to provide high-quality mesh reduction without having to leave the Unreal Editor.
    • Developers can quickly simplify meshes, generate LODs, and immediately see the results in their maps.

 The mesh has been reduced with a quality setting of 50%, resulting in similar looking geometry with a much lower triangle count.

Unreal Kismet Debugger

  • It is now possible to visualize Kismet node activation, set breakpoints that pause execution when nodes are activated, and step through sequences while running PIE!

    • With this brand new Kismet debugger, you can:
    • Visualize the flow of your Kismet sequence while your game is running.
    • Debug issues where nodes are being activated in the wrong order, not at the right time, not at all, or too much.
    • Step through your sequences one frame at a time and set breakpoints.
  • The Kismet debugger controls are located in the Kismet toolbar.

 

  • These features can help identify exactly what parts of a sequence are currently executing in your game and for what reasons.

 

  • Enabling the Kismet Debugger is done through the Enable Kismet Debugging button in the main editor toolbar.

Profiling, Performance, and Memory Improvements

  • Major memory and performance optimizations ship with the June UDK Beta.

  • The [STAT UNITGRAPH command](http://udn.epicgames.com/Three/StatsDescriptions.html#STAT UNITGRAPH) provides easy in-game visualization of performance data, making problem areas easy to detect during play.

 

  • Gameplay Profiler improvements include:
    • You can now see time spent in native cycle counter scopes on the game thread.
    • Data types are color-coded, so it’s easy to distinguish levels, actors, script functions, and so on.
    • The Gameplay Profiler can now display an asset associated with an actor or component.

 

Unreal Landscape

  • Unreal Landscape now supports decals, which makes it possible to add dynamic effects such as tire tracks or footsteps to surfaces.

  • Landscape now has a custom texture brush that enables you to control the shape of the brush using a texture. Paint layer weights, noise, etc. with a brush of any shape.

 

  • A preview of the texture in use is now displayed with brush settings.

 

Additional Improvements

  • The Height Fog shader has been optimized.

  • Editor Preferences have been moved to the main menu bar for easy access!
