This tutorial walks through the setup, material application and rendering of an alarm clock. You'll see how to properly set up the components of the alarm clock using shapes and instances, edit some of the mesh with the polygon tools, apply some materials, and then walk through a rendering.
This basics video covers the use of spot lights in addition to some basic rendering functions.
This set of three short tutorials are for those brand new to both 3D and Design3D SE. In these short videos basic introductions to these topics are discussed.: 1, grids and the active grid; 2, creating objects; 3, cameras
This video explains what the specular parameter is in the materials dialog. This will help you to understand how to use it, along with the Smoothness parameter which influences it.
Here are two videos which show how to control the lighting in a scene by adjusting several material channels. The diffuse and ambient amount channels govern how much light is absorbed or reflected back to the viewer. These videos show how to use them.
This tutorial walks through a couple of the rendering parameters in the Render dialog box that deal with light, specifically with radiosity/global illumination.
