All modeled and rendered in modo. The products and boxes are modeled out of polygons. The boxes are made in the 3D program 'flat'. Using cutter guides as reference templates. I then make the UV! All I have to do next is to fold the box up... just like the real thing! As you can see from the left and right boxes they have all the right folds! The UV allows me the place the package design visuals/artwork straight onto the products with no distortion too the labels.

Once the first design is applied, all other pack designs can be applied with ease!
