April UDK Beta Released

**Flak** · 04-21-2010, 03:52 PM

The UDK licensing site is now open! Signing up as a commercial UDK developer is a very simple process that takes little time to complete. Anyone can purchase a UDK commercial license through www.udk.com/licensing.

Please be aware that the UDN website updates overnight (US) and some pages may not yet be available.

Many notable additions and improvements are included with this month’s release:

Unreal Engine 3’s new procedural building system enables users to very quickly create and edit good looking city buildings.
UTGame, the example game content included with UDK, has fully transitioned to UDKGame. All content included with UDK (except for skeletal meshes) can now be used by commercial UDK games and applications.
Cascaded shadow maps, dynamically shadowed translucency, and improved unbuilt lighting previews have been added to the lighting system.
A new map, GDC_FeaturesDemo, is now included with UDK.
The perspective viewport now supports depth dependent halos, making wireframe views much easier to read.
The new asset consolidation tool provides a simple way within the editor to consolidate multiple assets into one asset.
Also included are dozens of upgrades to the Unreal Editor, Unreal Matinee, Unreal Content Browser, and other Unreal Engine systems and tools.

April 2010 Beta Upgrade Notes

UTGame
- Renamed to UDKGame
  - All the tools now refer to this game as 'UDKGame'
  - UDK content directory is now named UDKGame, not UTGame.
- All UTGame native functionality is now either removed, moved to UnrealScript, or moved to UDKBase if more generally useful.
  - This means that the UTGame package can be removed by removing it from the EditPackages and not referencing any classes from it in your maps or ini files.
- Removed unused UTGame properties and functionality.
- UDKPawn client update smoothing using mesh translation
  - Controllable via new UDKPawn properties bSmoothNetUpdates, MaxSmoothNetUpdateDist, NoSmoothNetUpdateDist, and SmoothNetUpdateTime.

- Removed obsolete localization files from UDKGame, and added UDKGameUI.int with UDKBase specific localization references.
- Removed hoverboard towing support.
- Hint loading system (for loading movies) is no longer hard-coded, and is now useable by other UDK apps.
- Separated UDK versions of ini files from UTGame specific ini entries, adding new DefaultEditorUDK.ini, DefaultEngineUDKBase.ini, and DefaultGameUDK.ini files.

Awesome. I've just spent ages looking into proc buildings - it hasn't gone so well so this is perfect timing. Looking forward to using it.

Enjoy.

Hmm renaming of UTGame has screwed up my project. I tried changing references to UDKGame but I can't seem to get it working (I used this tutorial to create my own project folder and it was working fine until April release).

Can anyone please post a short/quick guide here about creating own custom game folders?

**DELUXEnized** · 05-09-2010, 05:43 PM

Hello,

I have just installed UDK April Beta and now I am encountering some problems.

The material editor is not working anymore. I don't see the primary node and I don't see any expressions I have added. It just shows a grey background. This happens if I create a new material and also if I try to edit a material from my packages and the UDK included materials.

Furthermore if I look at the details of my materials (from my package) in the content browser, it just shows 0 instructions although there have been instructions in the old UDK version (and still are if I open the same package in old UDK). This just happens to my materials, the UDK materials still show instructions but if I open them, same problem as described above, just grey background, no nodes in the editor.

anyone the same problem?

**tomacmuni** · 05-20-2010, 12:25 AM

When I install I get an error with UE3dRedist.exe
even though 2005 and 2008 Sp1 Microsoft Visual C++ has already been installed.
The editor apprently runs ok, apart from the blank editor windows.

The installation is on Windows XP Sp3 and tried it on Vista and that works.
But I need it to work on XP ...

While installing the UDK, the error is something like: VCRedist x86 failed to install.

[Edit: When installing in XP Sp3 the UDK March 2010 installer kept giving errors about vcredist 2008 ... still, it would run the game editor but the material editor and kistmet show only empty blankness (even if there is content in an opened material etc).

After installing with the vcredist errror, I went into C:/UDK/UDK-2010-04/Binaries/Windows/ and copied all of its contents straight out to C:
Then I ran the UE3Redist.exe from C:/ and it worked whereas when it autoran from the UDK installer it didn't work.

However, besides the fact that now there are no errors when installing, the material editor and kismet windows remain blank, dark grey and depressing.]
