Thanks guys
Yup Podium has come a far way since December last year, the above were done with the new version 1.5 beta (available to all registered users) which has many new features like clipmapping (alpha maps), bump mapping, scripting, better light and sun control, recognition of front faces even if they are not all facing out etc (there are more but thats all I can remember) and it's free to anyone that owns the basic version.
As mentioned the above renders where done in 1 to 4 minutes on average, only Vivid logo was added, so these are all RAW renders.
Hopefully very soon a new texture tool and figure creator will be available (my software, independant of Podium, but within the Sketchup program) that will make mapping odd shapes a breeze as well as introducing mid size poly people into models that can be textured in detail for use in foreground requirements.
I will keep you posted.
