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.
I finally managed to implement full support of rotatable textures. This is a major breakthrough for all kind of effects and features (beams, trails, sprites, sparks, volume effects, Menu/GUI/Interfaces) and also has the following benefits: I don't need plane meshes anymore to archieve this effect and the performance is increased.
