The representation of finished models in SketchUp always has a drawn character. This is partly due to the goal of SketchUp, which is reflected in the name of the program, and partly because it lacks a renderer that is not part of the program. Additionally, many users miss the ability to represent models more realistically with lights and lighting effects. To create a design of high quality, even to the point of photorealism, one must rely on an additional program, such as Render[in]. As a so-called plug-in, Render[in] is directly integrated into SketchUp and does not need to be launched as a separate program. This means that importing SketchUp files is not necessary; users continue to work directly in SketchUp and see all changes to the model live in a small preview window.
