Thanks for the reply and that would certainly be a good place to start in development terms, and I intend to do that - actually to re-start, since I'd been working through them already in the past. That part is fine.

Would still like to find even one good terrain tutorial that's current and shows how to use the current terrain system from a designer's perspective (I'm a designer type :-p) - I'd think that's more of a design thing than a coding thing. Anything like that around that I might have missed?
