Epic Games Releases May 2011 Unreal Development Kit Beta

作者 Unreal Engine


Epic Games, Inc. has released the May 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 share a case study on using UDK for architectural previsualization. This story details how one university student created a highly realistic, interactive virtual walk-through of a modern architectural schematic using UDK. In his first encounter with Unreal Engine 3, Luigi Russo created “realistically scaled models that you can walk inside, offering the best possible view of the project. UDK was a lot easier to learn than I could have imagined.”

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.
