I'm really excited about one of the latest and greatest SketchUp books. It's called Rendering in SkechUp by Daniel Tal...and comes in at a whopping 640 pages. That is a lot of incredible info from one of the masters. And unbelievably, it's under $30 at Amazon. At that price, it needs to be in your library, if only to browse at the lovely pictures.
Feel overwhelmed? As usual, I'll be distilling the best tips from it for my rendering classes.
