The December 2009 UDK Beta upgrade notes are as follows.

New UDK features and tools:

    <*>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. <*> http://udn.epicgames.com/Three/DLLBind.html

- 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.

~ 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:

    <*>Custom lighting can emulate Phong for two-sided materials via new“TwoSidedSign” node.
