You can load images and textures into the 3D
               View as stencils and project part or all of the image
            as paint onto your sculpted model using the Projection tool.
         
         
            - From the Stencil tray,
               select a stencil image you want to load as a paint projection image.
               The stencil image is
                  loaded into the center of the 3D View.
                  You can scale, rotate, and tile the stencil image in its current
                  location (in addition, you can dolly, track, or tumble the camera)
                  to position the stencil and model in relation to each other prior
                  to using the Projection tool.
                
- Select the Projection tool
               from the Paint Tools tray.
            
- Stroke across the stencil image where
               you want it applied as paint to your model.
               The stencil disappears
                  from view as you stroke, but the effect of the stencil appears on
                  the model. To show the stencil image when you stroke, turn off the Hide
                     When Sculpt property in the Advanced section
                  of the Projection properties. 
                NoteIt is necessary to
                     have at least one paint layer in order to paint on a model. The
                     first time you paint on a model, the  Create New Paint Layer window
                     appears unless a paint layer already exists and is selected. For
                     more information, see  Create a new paint layer.
                   
 
- When you are finished using the Projection tool,
               click the Off icon in the Stencil tray
               to unload the stencil from the 3D View,
               otherwise the stencil remains active. (You can hide the display
               of the stencil temporarily by pressing Q.)
            
NoteThe default color
               for the Projection tool is white. This
               ensures that the original color of the stencil image is applied
               when you stroke over a stencil. You can tint the color of the image
               by modifying the Color property for the Projection tool.
