# Unit 2 - Real-time Previsualization

In this unit, you’ll learn about previsualization in Unity by modeling a city based on a reference sketch. In the process you’ll learn about configuring the look of the Editor, working with Primitives, Probuilder shapes, creating Materials and adjusting lighting.

Previsualization (pre-vis), is an invaluable process in the cinematic pipeline that allows you to quickly see how a 3D Scene will look before animation, filming, or asset production begins. A strong previsualization process gives a creative director the freedom to rapidly iterate ideas without reshoots or re-developing assets once a project enters production.
