To ensure the lessons work as described, do these steps before beginning:
If you just finished Lesson 1 in this chapter you may be presented with a window asking if you wish to Save previous paint effects. Select No.
If the Paint Effects Shelf tab does not appear as part of the shelf set, see the Maya Help for Shelves. (For Linux users, any new shelves do not load by default.)
Regardless of your operating system, the Paint Effects preset brushes are accessible from the Visor panel. (From a view panel, select Panels > Panel > Visor.)
