In some projects, it may be required that we create a quick conceptual illustration of an architectural design. These easy illustrations are an economical way to communicate a variety of construction options to the client and sometimes, it can be decisive for the final visualization. The lighting in Lumion may not always be sufficient to outline the 3D models' details and the shadows may generate ambiguous surface details and profiles. With the Cartoon effect, we can create these conceptual illustrations not only as colored sketches, but also as black and white illustrations.
