Effects are easy to achieve with the Unreal material system, for instance, here's the material
for a metal barrel. You can see in the preview on the left that it has a base color, shiny

the middle is what describes how the surface looks, and that's what you're going to learn

Before you create a new material you'll need a place to test it.
1. Create a new level that's a simple BSP room with a light in it, build lighing, and save
it as DM-MaterialTest.udk .
