There are 3 things that I find very challenging about using the integrated rendering features.

1. Modifying several material aspects is complicated, and the words used, although accurate, don't always convey meaning to me. Where is shiny metal, gloss, roughness? Maybe, renaming some of the properties could be helpful. Or use industry standard naming for material characteristics. It could help to bridge the gap.

2. Applying graphics is a chore and a half. WHy can't I just, (Mac OS X) drag a graphic and drop onto a surface or a solid? and/or select a graphic as done from the media tab in Apple's Pages? (see attached)

3. Render seems to use only one processor. Why not all of available?
