This tutorial goes over generating a simple scene and lighting it a few different ways. The scene will be a typical German apartment with white walls, wood flooring and some furniture from Ikea. We won't be modelling the garage with an Audi, dog called Schatzi and traditional lederhosen.
This tutorial was done for SketchUp 2013 free version; your SketchUp may look slightly different, and basic familiarity with SketchUp (e.g. navigation and selection) is assumed.
