It contains the Vue Artist line objects, and the default plants. Objects are useless, they were probably made at the time of Vue 3 (if not before!), but you'll want the plants, even if the quality is far from consistent between species (some date back to Vue 2!), but they are needed if you want to buy some of the plants from Cornucopia.

To know exactly what's included, download a demo of Vue Esprit, and check out the collections.
