# Environmental Design Techniques ---  > Art by Andrei Egorov --- ### Planning  --- ### Modeling and Texturing Workflow - We go to the Internet, look for buildings, and split them into modules. Each of my modules equals 2. 2,6,8,10... meters. - There are a lot of cars in the city. If I textured each car uniquely, it would take a lot of time. So I decided to create one car, one truck, and one bus, but use masks to create variations. - Using one car and two masks we can create many cars with different colors and damage. - For texturing cars, I used layered materials. This allowed me to add as many layers as I wanted. ---  - For my scene, I chose the type of lighting in shadow-light-shadow.
