decal improvements
- lit translucent decals are now supported
  - allows much better blending of decal edges into the environment
- shadowmap support for decals
  - works for both static and dynamic shadow maps and allows for decals to receive shadows from dominant directional lights as well as toggleable lights
  - works when decal is attached to texture and vertex lightmapped
Animtrails: animation driven trail emitters
- allows artists to easily create particle trails following animations

ongoing UTGame de-nativization
- Moving UTGame specific C++ functionality that didn't need to be in C++ back into UnrealScript
- This makes it easier for UDK developers to see how we implemented this functionality, and has also resulted in new engine functionality being exposed to script.
  - Notable examples include the new SVehicle physics interface functions and making it possible to tick skeletal controllers and UTUIScenes in script.
fixed Lightmass generating directional lighting being flipped in the texture's V direction

You can download the MyDiff between December and the January release here:

It's a download now because there are soo many changes the number of characters is to high for this post. Because of this, it is recommended to port over your project if you work of the UDK directory.

Enjoy.

It seems that the January build messes up the jerry-rigged SSE2 fix.

I'm not 100% sure of this but I'll keep trying to find out.

hi lennard, yeah seems like it's better to port my project instead of replacing files, i have a question for this, how can i "send" or export some custom postprocess fx and materials from one library to the new library in the january version? thanks in advance!
