dvd box mock-up - it is not 3d - it is psd, and there is no raster layer - only vector!
if you ever had a look at the psd you could see that i have exploited each and every features of cs4 including smart object, vector mask feather etc.
for ease of customization, i recorded several actions so that i can make change of front, sides and top layers at a single click.
want the psd? here is the link - http://graphicriver.net/item/dvd-box/57396
