Scrapbooks are a major upgrade to the old Copy/Paste tools.
Scrapbooks are a new Asset Type that provide the ability to copy and save a part of your route, then reuse that scene in other routes.
The
Scrapbook Brush Tool turns your old "Ground Texture Paint Brush" into a "Swiss Army Knife Brush" that paints everything contained within the currently selected Scrapbook, including Ground, Textures, Scenery, Splines, everything.
You can also decide which elements are painted and which are not by expanding and using the Scrapbook Filters.
