Window coverings

Window covering materials include both soft window coverings (drapes, valances, café curtains), and hard window coverings (shades and blinds).

Window covering materials specify a window-covering style file ( .vnw file extension), a special data file similar to a vignette, containing mask, illumination, layout, and texturing data defining the window covering.

vnw files do not include the color and texture (fabric) for the window covering. This information is specified separately, similar to repeatable textures.

Window covering materials can only be applied to Window Covering Frame Objects, which are overlapping objects.
