In this unit, you will extend your understanding of 3D modelling by demonstrating skills and knowledge in grey box level design and basic UV mapping techniques for the application of textures to a 3D model. You will learn how to create simple 3D environments that illustrate how your mechanics will function, employ modular level design techniques that allow for rapid prototyping and the quick iteration and play testing of your level design ideas in a game engine. By the end of this subject, you will be able to create, evaluate and improve on your level design environments and understand the export process between a 3D modelling package and a game engine.
