Was working on a high key lighting technique (this technique was used by Lucas during his 1st Star Wars movie).
So I decided to use R2. Found the model at http://tf3dm.com/3d-model/r2d2-21038.html (hat tip).
I redid the normal map and followed the tutorial at http://www.creativeshrimp.com/high-key-lighting-in-blender-book-03.html for the lighting setup.
