We had extra models for Circuitree that were not implemented for the first project. I had to check each model (5 rocks, 2 plants) to see if their normals were correct. For the first project, Circuitree's trees normals were inverted. That's why the the models were missing a few faces. Oscar also had to fix the normals for each tree. He separated them into different parts. I reconstructed them by putting each of the tree parts together in an irregular manner.
