Screws.

Well, this is the result of a tutorial I made on how to make a screw in Blender. Getting the lighting and the materials right was really tough, especially the screws. Surprisingly enough, the wood texture is entirely procedural. I have to thank the map Zone Team for making such an amazing open source program. It's like Blender's material node editor times 4. The screws are just a dark grey with more thank .5 reflection. I did the render using Yafray, and everything is modeled in, of course, Blender.
