Render is the picture you get once your scene is finished being built, incase you didn't know. :) As for RWB4, even though it's for 4 it all applies to Bryce 5 and IMO is a lot better than the handbook. The only things you won't find in RWB4 is the tree lab (good tutorial at www.brycetech.com) and metaballs (lot's of info on this forum, search "metaballs"). RWB4 is almost 1000 pages going in depth on how things work, what doesn't work the way the manual states and lots of examples, tutorials, etc as well as a content disk. All for a very low price. I think I should start getting commission for every RWB4 I get someone to buy. LOL
