These model has been made in Maya using standard polygon techniques with some sculpting addons. The environment is a old scene I used for a client who needed an interior render of his living room. This Chesterfield 3d model armchair is a good subject if you want to play with DOF inside Mental Ray rendering. Complex Mental Ray fur it was also used to make a plus to the overal appeal.
