Here's an Ad I quickly created (see attached). I created the cover art in The Art Center. I then switched over to the PhotoRealistic center and imported the artwork onto one of the 3D models (by right clicking over the model). Next, I exported the 3D image (using the little camera icon at the bottom right of the screen) as a Jpeg. I then imported the new 3D image back into The Art Center (by choosing "import" from the file menu). I then added the text and other elements found in image 2!
