As I posted above, I used another model.  The Destroyed City didn't export well as an obj.  There were weld and other mesh issues.  The cheapest and easiest way to get dsf product (DS native format prior to DSON and DS4.5) is to get D3D's free script and the DSON importer.  You don't have to worry about export and import issues. 

The toolbox has a number of different tools.  You would need to decide if you need some or all of them.  I bought it for the dsf to obj conversion which converts dsf format to obj format.  I use some of the other scripts at times but not as frequently.  The toolbox isn't as useful as it once was since DAZ changed from dsf to duf.

DS3, Light Dome Pro and Mood Master2 can create those promo's.  Light Dome Pro and Mood Master were two of Dreamlight's better plugins.  It's too bad he didn't update them for DS4.  Mood Master was much easier to use than atmospheric cameras.
