Basic Free Render?

 From:  Frenchy Pilou (PILOU)
Now you have the very simple Shaderlight in beta so free as plugin for free Google Sketchup
(so export from MOi in Skp format)
site of ShaderLlight

Else you have Kerkythea but some medium complexity ;) (stand alone or plugin of free Google Sketchup)

The more easy is Podium
in free: limitation is 500*500
(always plugin of free Google Sketchup ;)
