Before going into Zbrush with my barrier. I went to Norwich and had a look at some of the buildings, walls and paths for some insight on the style and the look of real life acid corrosion, the impact of damage and age.
Looking at them allowed me to focus more clearly on the way cracks and damaged are formed on environmental surfaces but it mainly depends on what created the damage. Most damage seen on statues and buildings is usually caused by acid rain which corrodes the rock used to make the structures.
I believe that this has helped me get a better understanding of damaged surfaces and I’ll definitely look at more again when designing a damaged environmental objects or anything that is supposed to look damaged.
