IMPORTANT: Vasari includes a built in material library that includes low resolution textures that are suitable for basic rendering. To render a view with high resolution textures, you must have an Autodesk 2012 product installed with the AEC materials library.
In Vasari, the process of rendering a 3D view is as follows. (The first 4 steps can be performed in any order.)
