The Unreal Tournament SDK is state-of-the-art Toolset / Engine Enhancement for retail Unreal Tournament, that let's you create anything you want. Sci-Fi Battle Scenes, a Strategy Game, a Fun Mod, Survival-Horror Shooter, Simulations - Everything. It will also include a Sandbox showcasing the New Possibilities via bundled Mini-Mods / Demos made by Fans and me. It enhances the render engine, gameplay, unreal script features and anything UT Veterans ever dreamed off. It is completely Open Source, free for noncommercial use.
The Download for the Demo Version of the Extension Pack for UT99. It contains mostly new basic features like Emitters and Lensflares and can be seen as some kind of Preview but not as an SDK like the Final Version.
The Public Beta Version contains: Basic Emitters, Basic Spritebeams, ~ 20 Example Classes, some Documentation, 1 small Test-Map, Basic Projectors, Skin Overlayers, 2 Util-Classes, Installer (if UMOD Download), Lensflares, Dynamic Coronas, UScript Source Classes, Content Source, Options Menu and so one. The Beta is very small (3 MB in size) thus it's recommended for Modem/ISDN Users because the Final will probably be ~ 100 MB in size!
I know that this isn't that much, but it's just Demo/Beta Version so I recommend to develope with the stuff in the Final Version. It'll contain 5x the amount of classes used in the Beta (~ 250 Classes), many Test (where you can freely test nearly everything), Example (here pre-made examples are shown in a fitting environment) and Tutorial Maps (levels used for the tutorials), a Class Reference (EACH class is listed + overviews), Class Tutorials/How-To-use Documentation, a new Renderer (to provide hardcoded features like Bloom, or the new Mesh System), Tools (like the Export/Manager Program for the Mesh System) and many other surprises..
