On more interesting notes, it will go over visual effects in UDK and how to edit them using the Cascade tool. It will also include how to set up lighting above and beyond the dominant directional light that the preset templates include. Finally, it will give a brief overview of the post-processing system, which can really give our game some life.  Filling Out your World with Details Now that we've got a rough idea of our level layout, let's add some details. In this chapter, we will cover the following topics: Static meshesParticle effectsLightingPost processing Each of these features of UDK has a role to play in making our level feel more like a unique world.

Shortcut Installing UDK should automatically create a shortcut in the start menu, but there's a possibility that it might not be created. If that's the case, or there's any difficulty getting into the editor, here's how to make a shortcut to the editor. Navigating back to UDK, we're now going into the Binaries folder, and then into the Win32 folder. exe. We'll find that if we double-click on and run that executable file, it won't open any sort of development environment, but will instead open up what appears to be the main menu of a game of some sort.

With that in mind, we should probably name our new particle system as Dust, or something along those lines. Clicking on OK will create our new particle system and drop us into Cascade with the default template as in the following screenshot: What we're looking at can be a little overwhelming if we don't know what we're doing. So let's walk through this step-by-step and get acquainted with Cascade. First thing's first: we need to get rid of those blue, red, and green plus signs. So, let's replace it with a good dust material.
