Hi Pilou,

Sculptris looks similar to this one : http://www.cbmodelpro.com/
I will stop my self to look at polygon mesh modeling, its so hard :(

Yes, I know Sketchup.
Its polygon, but its different.
Usually people use it to create "hard" model, not organic model.
Also the UI is Windows / Microsoft Style.
So its more easy to use.

Are you expert ( daily use ) in polygon modeling software today ?
