This is the second part of my tutorials on rendering using the cycles rendering engine in Blender. In this part we continue from the previous tutorial where we made a simple floor with grid and lighting effect underneath. Now we will build a simple wall that we can effectively UV Unwrap, texture with a realistic metal texture material and then add a roof containing lights to give a final rendered output that looks pretty realistic considering the little work involved in creating this, the whole scene took less than an hour. Although far from finished it gives a good starting to point to develop the model further should you wish.
