We will start by talking about modularity theory and its benefits and disadvantages, and offer some solutions to cure some problems. Then start working on the planning stage to make sure that we have a strong ground to stand on top of. Then we create the block-out to make sure that our ideas are correct, then start to add iteration on top of iteration to finalize the environment. In the way, we will learn about tiling geometry, tiling materials, displacing simple geometry to create complex details, creating good-looking materials, lighting and many more.
