Enable the Grease Pencil by clicking Draw, Line, Poly or Erase from the Tool Shelf T. A new layer will be automatically added for you to draw on.
A new layer can be added from the Grease Pencil panel in the Properties region. This panel can also be used to customize the color, opacity and thickness of the pencil lines. Changes to these settings will affect all strokes on the current layer.
Grease Pencil sketches can be converted to editable geometry and used to aid the animation process.
The Tool Shelf provides a number of options for drawing with the Grease Pencil which are detailed below.
- Draw D-LMB
- Draw a new stroke (multiple short, connected lines). The stroke will finish when you release the mouse button.
- Line Ctrl-D-LMB
- Draw a new line in rubber band mode. The line will finish when you release the mouse button.
- Poly Ctrl-D-RMB
- Draw connected lines by clicking on position you want to add the next point. Lines will be automatically added to connect the two points. Holding LMB down and sliding mouse lets you place the new point/segment preview. The transformation of the point is locked to X/Y axis set by initial direction of the mouse movement.
- Erase D-RMB, Eraser
Erases segments of strokes that fall within the radius of the eraser “brush” (with a linear falloff from the center of the eraser circle). The erasing will continue until the mouse button is released, while trying to reduce the thickness of strokes before removing them. The eraser operates on all visible and editable layers. If begun with Erase, either RMB or LMB will erase strokes. Its cursor is a red circle with a dashed outline.
The size of the eraser “brush” can be controlled with Wheel, or with NumpadPlus and NumpadMinus, while still holding RMB.
- Insert Blank Frame D-B
- This operator adds a new frame with nothing in it on the current frame. If there is already a frame there, all existing frames are shifted one frame later.
- Delete Frame(s) D-X
- Remove all active frames if they are not locked.
With the “Additive Drawing” option enabled the active frame’s strokes will be carried over/copied if you start drawing on an empty frame (i.e. one without any keyframe already). This saves the effort of keeping a Dope Sheet open, and having to remember to duplicate the current frame before starting to draw the next pose (or risk managing to draw the perfect pose, but without everything else).
This option makes it easier to animate shots where you’re building on a result from a previous frame. Examples of cases where this comes in handy include animating facial expressions (when all outlines are on the same layer), or animating “growing” things (e.g. vines, or concentric circles growing from a central point).
Even without this option enabled, this is the default behavior when using the eraser on an “empty” frame. This makes it easier to do shots where you’re just changing parts of the facial expression, or if you’re animating an “eraser” effect.
Continuous Drawing allows for rapid sketching with the Grease Pencil when multiple strokes are desired. So that you only have to hold D once for the first stroke. Besides the checkbox Continuous Drawing is also enabled if the D key is released while pressing LMB. The eraser for one-off strokes (RMB) is still available. Note that with the Eraser both LMB or RMB can be used when drawing has started.
Use Esc or Return or clicking outside the current viewport (e.g. another region or editor) to exit the mode. Continuous drawing can be disabled using E key in order to get fast access to sculpt mode.
Draw on Back¶
New strokes are moved behind the drawing when confirming the drawing tool (lowered to the bottom of the stack).
Defines how the strokes are converted to 3D (or 2D) space.
- New strokes are placed in screen space (2D) and are locked to the view.
New strokes are drawn in 3D space, with position determined by the 3D cursor and the view rotation at the time of drawing. Cursor is available as an option in the UV/Image Editor but it functions identically to the View option. (3D View only)
- Lock axis
- Lock projection to a specified axis.
- New strokes are drawn in 3D space, with their position projected onto the first visible surface. (3D View only)
- New strokes are drawn in 3D space, with their position projected onto existing visible strokes. Note that strokes created with View are not in 3D space and are not considered for this projection. (3D View only)
- Only Endpoints
- Applies the drawing setting only to the endpoints of the stroke. The part of the stroke between the endpoints is adjusted to lie on a plane passing through the endpoints.
Notes For Tablet Users:
- The thickness of a stroke at a particular point is affected by the pressure used when drawing that part of the stroke.
- The “eraser” end of the stylus can be used to erase strokes.
- Enable Editing
- See Stroke Edit Mode. An overlay is displayed in the top-right corner of editors when enabled.
