The archive is a separate folder "stepladder" with a ladder and a folder "Picnic tins" cans with a picnic area. The latest previews are shown as boxes laid out on the files. To save all kinds of boxes in the file one at a time. Materials for these are there assigned to the entities of the same name. (For the import) all the way cleared, all the grid has the sweep. You can change the texture of the boxes on your own. PS: about the suitcases from the file "Picnic_tin_00", not sure it's for a picnic, but they are very much like me and even for storage subject suit))).
