This tutorial goes over taking the Diffuse texture from Lesson 3, and turning it into Normal and Specular maps. This does not teach many new artistic skills but there is important required reading so you know what you are doing.

The PSD files for all the tutorials can be downloaded from:

This tutorial is just over 30 minutes long.
Assignment:
Read the assigned reading. Then take the texture you created in Assignment 3, and go through the process laid out in the Tutorial, creating normal and specular maps. Then, post a render of your material (how to do so is shown in the tutorial), and upload your diffuse, normal, and specular maps. If you do not have a 3d modeling program, just upload your texture files to show me.
I will make a thread tomorrow to post the screenshot and 3 texture images in. After that, I will make a thread detailing the final assignment for the class.
Please post any questions pertaining to the assignment or class in this thread.

You will need to download and install the DDS/Normal Map plugin from nVidia:

Once you go through the process of creating a heightmap/normal map by hand, you can try CrazyBump which does a good job of automating the task.
