I've lived in Phoenix AZ all life and the scenery for the area is all wrong.  I even purchased "Real Scene 2004" to hopefully fix it, but it's even worse.  There is a major freeway and some major roads not even included.

1. I'm looking for ideas and help on how to go about fixing hte Phoenix area
2. What tools do I need
3. Where do I download the proper mapping of the area
4. How do I add in all the major features (major malls and such)
5. Can I design my own buildings and what would I use?  I have both Rhino 3D and Cinema 4D, can I use them?

As much help as possible would be great, thanks
