Understanding Autodesk Revit Materials18 Sep, 2013 By: Daniel Stine
Learn how to manipulate materials skillfully, and you'll be able to get the results you want from Revit.
Notice, in the image below, when the material appearance is set to Tiles, it is possible to change Tile Appearance to an image. This allows you to do some cool stuff: You can make a material to be a concrete walk, wood wall, or ceiling panelling, and much more.
In the image below, you can see a nested Texture Editor (notice the arrow) for the Tile Appearance settings.
Regarding rendering speed, the Autodesk Wiki Help page includes the following note:
The material render appearances that require the most time to render are (from slower to slowest): metallic paint, flecked metal, hammered metal, water, frosted glass, and perforated metal. Slower render times for these materials are proportional to how much of the scene they cover.

The information below is an overview of several of the material settings and options.
