MATERIALS PREP

For this exercise, I've recreated the same materials as Pablo did. I especially find the AO and Edges materials very useful. I've also created four new materials: The first adds dust to surfaces on faces that follow the Z-axis. The second adds mud from the ground with a gradient. The third is intended to add soot to chimneys, also with a gradient on the Z-axis. The fourth and final material attempts to recreate a wet surface. I've decided not to create more specific materials because I believe that by using all the ones I've created as a base, they can be modified to create many others quickly.
