everything is 3d all done in softimage, used tgen, ICE and normal modeling.
Trees are made with t-Gen, the grass is create grass compound , different grass patches with colour variation
Flowers are T-gen too, the purple plant is modeled, the tiny ocean on the back is aa ocean (well its not much visible:p)
Render time took 3 hours and 40, Mental Ray, it took a bit because of grass and AA sampling settings.
