January UDK Beta Released

[Flak]

Epic Games has released the January 2010 UDK Beta, a free, updated version of the Unreal Development Kit (UDK).

Epic is committed to providing the UDK community with regular software releases free of charge, and the latest beta is available now at www.udk.com/download.

Do you need to get your UDK game in front of a publisher? Epic wants to hear from you!

An extensive list of new additions and improvements included with this version is available at:

• 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
  • http://udn.epicgames.com/Three/AnimTrails.html
• 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

Thank you

I really like the updated UDN documentation, very useful for me. Thank you guys you're awesome! =)

[robin1232]

if I install this, would it delete my projects?

[squall789]

Awesome!.

The update Wont ruin your projects and infact it will even install inside a new folder, though I would always recommend backing up all your stuff 1st, just to be on the safe side.

I wasnt sure if the update was out as its not on the News page, Only the Download page, which I generally don't check if the news page gives me no indication to.

Upgrade: Install UDK to new directory, copy your stuff into new directory, adjust your config files as needed.

Other way to upgrade: Install UDK over itself, and adjust your config files as needed.

I keep all the added files for my projects on subversion servers, so i just installed the new release over the old one, opened my project folder, hit Revert to revert the changed config files, then deleted UT*.ini

[Nysuatro]

Hell yeah, keep up the good work

Anyone know how to work with the STATS functions, I remember one time seeing heat maps of the player deaths in the map drawn out as an image.. anyhow .. neat function but any advice on how to call this or example code

[chri882]

Yeah!! Was waiting It!

Thanks Epic, you guys are the best!

This beta removes the commandlet "UTReplaceActor". Haven't checked to see if it also removed the corresponding function in the Editor, or if the Editor function for doing that supercedes the commandlet, and that's why it was removed.

This beta also removes Delayed Switch from Kismet. =( Why? It was so usefull!
I will return to my previos November BETA-2...

[Hyncharas]

I think it's a bit much to have a new 500MB-odd file every month if you already have the UDK. They should make a smaller hotfix version as well for those who can't afford the bandwidth.

Yeha, an update patcher will be very cool, as the natural selection 2 editor.

[ArtiomVIP]

Can anyone from Epic explane, why did you remove DelaySwitch? And RangeSwitch?
DelaySwitch is in 3Buzz lessons too, they are not correct anymore.
And I should recreate a lot of my scripts now... Why did you do this???

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

MyDiff-December-January.txt

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.

Thanks LennardF1989 !
I note that postprocess volume work now with blur :
