Optimizing textures in Unreal Development Kit and some of the key things to remember when importing textures into UDK. We’ll look at a few ways to save memory by extracting Specular maps from Diffuse maps, as well as working with LOD settings to optimize game play.
Speedtree is basically a 3d application used for creating or modeling Dynamic and realistic Trees and Foliage for games which comes free with Unreal Develop Kit (UDK). If you have UDK installed in your machine then you don’t have to download Speedtree because it gets installed with UDK but if you really want to use Speedtree in other 3D application as well then you’ll have to buy it from their website. For this tutorial you need to have atleast Unreal Development Kit installed on your machine.
