- DLLBind feature
* This significant feature enables UnrealScript to call functions implemented in Windows DLLs.
* UDK users can now write native C++ code to interface with script.
* “DLLBind” gives users the ability to extend the functionality of UDK.
- Material vertex shader control
* Offset static mesh vertices from within the material using world position, vertex colors and “WindDirectionAndSpeed” data.
~ Artists can now modify vertex world position in the material editor, which allows arbitrary deformation effects and custom ambient animation for different types of objects.
~ “WindDirectionAndSpeed” is useful for obtaining wind parameters from any wind actors placed in the level, which can be changed at runtime.
- New visual-only “InteractiveFoliageActor”
* Simulate a spring based on input touch and damage forces.
~ Walk through tall grass and bushes, which will be pushed out of your way and then sway back when you stop pushing them.
~ Weapon projectile and explosion damage will also apply forces to the foliage actor.
* Extremely low performance impact; costs nearly the same as a static mesh and therefore can be used extensively.
~ Includes example videos for explosions, walking through fields and advanced foliage animations.
- New Unreal Editor features
* UDK users can now import 32-bit BMP images.
* View original, displayed, and effective texture resolution in the new Texture Info panel.
* Check out the many other editor upgrades here:

- ActorX has been updated to support 3ds Max 2010!
* UDK users using 3ds Max 2010 can now export skeletal meshes and animations to binary file formats that the Unreal Editor can import using the ActorX plugin.
* Find it in the /Binaries/Tools/ActorX directory.
- Custom lighting and transmission improvements
* Custom lighting can emulate Phong for two-sided materials via new “TwoSidedSign” node.
- In-game debugging tool
* "ToggleDebugCamera" now supports selection and shows all materials used by mesh components.
* UDK users can now select meshes at runtime to view what is in front of the player.
- Level Browser improvements
* New tagging and filtering system with keywords makes searching levels easier than ever before.
* Persistent level actors can now be easily hidden or shown.
* New "PIE Only Visible Levels" toolbar toggle limits which levels get loaded in PIE to only levels that are currently visible.
* New “Lock/Unlock/Hide/Show” settings for all levels via right mouse button (RMB) are now available.
* New "Find in Content Browser" option has been added to the Level Browser.
- Unreal Kismet upgrades
* Kismet editor now has navigation history. Handy “Back” and “Forward” buttons make it easy to toggle between actions in the history log.
* Dropping Kismet nodes down on top of ports now auto-wires the node.
* New "Select in Level" option to Kismet right-click menu is now available.
- Particle improvements
* New camera-facing options for mesh emitters will override “AxisLock” settings.
- Unreal Lightmass
* Scene data exported to Lightmass is now compressed.
~ Reduces disk usage and network bandwidth.
~ Increases speed of Lightmass startup.
- Miscellaneous editor improvements and fixes
* Greatly improved “Convert Light” tool now supports all light types. Simply right-click on lights in the level viewport to convert them to other types of light.
* New material for geometry mode editing makes it much easier to align volumes and BSP in the world: http://udn.epicgames.com/Three/ContentBlog.html#New Geometry Mode Texture (11/30/2009)
* AnimSet Editor log spew has been fixed.
* UDK users can now build old UE3 lighting on SM2 cards.
- BSP and "Accept Lights" change
* Lights no longer "bleed" through BSP corners.
January release is out now. Hopefully there won't be multiple versions of it, like there apparently were with December. (NVidia's site was distributing a build with a different version # than the official site)
