Stencil properties

On: Turns the stencil on or off.
Image: Displays a thumbnail view of the currently loaded stencil image.
File: Displays the file path for the image loaded on the stencil. The stencil image is loaded either by clicking an image on the Stencil tray, clicking the Import button or using the Set Stencil button in the Image Browser.
Import: Launches the file browser for loading a stencil image into the active camera in3D View. Navigate to the directory and select Open. If using the Image Browser, select a thumbnail in the file browser and click the Set Image Plane icon on the Image Browser bar.
Transformation: This section lists the stencil’s Translation, Rotation and Scale properties and lets you enter values to change the position and scale of the stencil in the 3D View. Rotation occurs only within the camera viewing plane.
Invert Values: Inverts the values of the stencil image.
Hide When Sculpt: Hides the stencil while sculpting.
Flip Horizontal: Flips the stencil along its X axis.
Flip Vertical: Flips the stencil along its Y axis.
Use Tiles: Repeats the stencil image in X and Y screen space to fill the 3D View.
Show Tiles: Turns the display of the tiled stencil image on or off in 3D View.
Visibility: Controls the visibility of the stencil image in the 3D view. Visibility affects only the display and has no impact on the strength of the stencil.
Multiplier: Controls the strength of the stencil.
Offset: Offsets the stencil deformation relative to the surface of the model. The higher the number, the more vertices are raised and pulled out. The lower the number, the more they are pushed in. Set to the middle value (50), brushing over black pixels of the stencil image pushes vertices down, and brushing over white pixels pull vertices out.
