************ Introduction ************ .. figure:: /images/sculpt-paint_sculpting_introduction_brush-circle.png :align: center Brush cursor. Brush Control ============= - Set brush size :kbd:`F` - Set brush strength :kbd:`Shift-F` - Rotate brush texture :kbd:`Ctrl-F` You can then either adjust the value interactively or by typing in numbers. After pressing the hotkey move the mouse to increase/reduce the value (additionally with precision and/or snapping activated). Finally confirm (:kbd:`LMB`, :kbd:`Return`) or cancel (:kbd:`RMB`, :kbd:`Esc`). Selection Masking ================= If you have a complex mesh, it is sometimes not easy to paint on all vertices. Suppose you only want to paint on a small area of the Mesh and keep the rest untouched. This is where "selection masking" comes into play. When this mode is enabled, a brush will only paint on the selected vertices or faces. The option is available from the header of the 3D View (see icons surrounded by the yellow frame): .. figure:: /images/sculpt-paint_weight-paint_hide-mask_select.png You can choose between *Face Selection masking* (left button) and *Vertex selection masking* (right button). Selection masking has some advantages over the default paint mode: - The original mesh edges are shown, even when modifiers are active. - You can select faces to restrict painting to the vertices of the selected faces. Details About Selecting ----------------------- The following standard selection operations are supported: - :kbd:`RMB` -- Single faces. Use :kbd:`Shift-RMB` to select multiple. - :kbd:`A` -- All faces, also to deselect. - :kbd:`B` -- Box selection. - :kbd:`C` -- Circle select with brush. - :kbd:`L` -- Pick linked (under the mouse cursor). - :kbd:`Ctrl-L` -- Select linked. - :kbd:`Ctrl-I` -- Invert selection *Inverse*. Vertex Selection Masking ------------------------ .. admonition:: Reference :class: refbox :Mode: Vertex and Weight Paint Modes :Header: :menuselection:`Vertex Selection` :Hotkey: :kbd:`V` In this mode you can select one or more vertices and then paint only on the selection. All unselected vertices are protected from unintentional changes. .. figure:: /images/sculpt-paint_weight-paint_hide-mask_vertex-select.png Vertex Selection masking. .. _bpy.types.Mesh.use_paint_mask: Face Selection Masking ---------------------- .. admonition:: Reference :class: refbox :Mode: Texture, Vertex, and Weight Paint Modes :Header: :menuselection:`Paint Mask` The *Face Selection masking* allows you to select faces and limit the paint tool to those faces, very similar to Vertex selection masking. .. figure:: /images/sculpt-paint_weight-paint_hide-mask_face-select.png Face Selection masking. Hide/Unhide Faces ----------------- .. figure:: /images/sculpt-paint_weight-paint_hide-mask_face-select-hidden.png Hidden faces. You also can hide selected faces as in Edit Mode with the keyboard Shortcut :kbd:`H`, then paint on the remaining visible faces and finally unhide the hidden faces again by using :kbd:`Alt-H`. Hide/Unhide Vertices -------------------- You cannot directly hide selected faces in vertex mask selection mode. However, you can use a trick: #. First go to Face selection mask mode. #. Select the areas you want to hide and then hide the faces (as explained above). #. Switch back to Vertex Selection mask mode. Now the vertices belonging to the hidden Faces will remain hidden. The Clipping Region ------------------- To constrain the paint area further you can use the *Clipping Region*. Press :kbd:`Alt-B` and :kbd:`LMB`-drag a rectangular area. The selected area will be "cut out" as the area of interest. The rest of the 3D View gets hidden. .. figure:: /images/sculpt-paint_weight-paint_hide-mask_border-select.png The Clipping Region is used to select interesting parts for local painting. You make the entire mesh visible again by pressing :kbd:`Alt-B` a second time. All paint tools that use the view respect this clipping, including box select, and of course brush strokes.
