This texturing and rendering tutorial walks through the process of texturing a gum pack. It emphasizes the use of a tin type metal foil using normal maps to provide texture. Part of this tutorial also shows how to adjust the Lightdome for use in the rendering process.
Just for those that would like to experiment with NORMAL MAPPING here is a link to a freeware that creates normal maps from jpegs.
