A funny alternative to render something from Moi is using Podium and Google Sketchup!
Podium is a "plugin" of Google Sketchup
Why ? Because Podium is the more easy renderer to use!
Only 2 buttons ! Light and Reflect!
You select any anything you want and just move the 2 curseurs!
Can't be more simple!
In free use Podium image is 500*500 max http://www.suplugins.com/
Google Sketchchup is free! http://www.sketchup.com/?dlc=1
(pro version exist also ;)
