Asset Shelf ‣ Draw

The Draw brush allows you to draw free-hand strokes.

Brush Settings

Material

Data-block selector for the material.

Radius

The radius of the brush in pixels.

F allows you to change the brush size interactively by dragging the pointer or by typing a number then confirm.

(Size Pressure)

Adjusts the radius based on the stylus pressure when using a Graphics Tablet. The gradient of the pressure can be customized using the curve widget.

Strength

Control the stroke transparency (alpha). From fully transparent (0.0) to fully opaque (1.0).

You can change the brush strength interactively by pressing Shift-F in the 3D Viewport and then moving the pointer and then LMB. You can also enter the size numerically.

(Strength Pressure)

Adjusts the strength based on the stylus pressure when using a Graphics Tablet. The gradient of the pressure can be customized using the curve widget.

Caps Type

The shape of the start and end of the stroke.

Round:

Strokes start and stop with a curved shape.

Flat:

Strokes start and stop with a straight cutoff.

進階

Spacing

Controls the minimum spacing between points in the stroke as a percentage of the brush size.

A lower spacing is useful when doing fast movements. Normally this would generate less samples and lead to a larger spacing between points. When the spacing percentage is lowered, more points are generated to ensure the minimum spacing.

When drawing slowly, the point density is usually already high. In this case the spacing setting doesn't add new points. It only ensures a minimum spacing and won't remove points.

Active Smooth

The number of smoothing iterations to apply to the stroke while drawing.

角度

Direction of the input device that gives the maximum thickness to the stroke (0° for horizontal).

Factor

Amount of thickness reduction when the stroke is perpendicular to the Angle value.

Hardness

Amount of transparency (alpha) to apply from the border of the point to the center. Works only when the brush is using stroke materials of Dot or Box style.

Aspect X, Y

Controls the width and height of the alpha gradient.

Stroke

Post-Processing

Post-processing methods that are executed on the strokes when you finished drawing, right after releasing the LMB or Pen tip. You can toggle the use of post-processing using the checkbox in the section panel header.

Smooth

Strength of smoothing process on the points location along the stroke.

Iterations

The number of smoothing iterations to apply to the stroke.

Subdivision Steps

Number of subdivisions to apply to newly created strokes.

Simplify

Reduces final points numbers in the stroke with an adaptive algorithm.

Trim Strokes End

Automatically trim intersection strokes ends.

Outline

Activate the conversion of the newly created stroke to its outline.

Material

Material used for outline stroke.

Thickness

Thickness used for outline stroke.

Randomize

Adds randomness to the position of the points along the stroke. You can toggle the use of Randomize using the checkbox in the section panel header.

Radius

The amount of randomness to apply using the pressure of the input device.

Strength

The amount of randomness to apply to the stroke strength value (alpha).

UV

The amount of randomness to apply to the UV rotation.

Hue, Saturation, Value

Randomizes the hue, saturation, and value of the stroke's Color.

Jitter

The amount of jittering to add to the stroke.

Common Options

Stroke Random (stroke icon)

Use randomness only at stroke level.

(Use Pressure)

Uses the stylus pressure to control how strong the effect is. The gradient of the pressure can be customized using the curve widget.

Stabilize Stroke

Stabilize Stroke helps to reduce jitter of the strokes while drawing by delaying and correcting the location of points. You can toggle the use of Stabilize Stroke using the checkbox in the section panel header.

Radius

Minimum distance from the last point before the stroke continues.

Factor

A smooth factor, where higher values result in smoother strokes but the drawing sensation feels like as if you were pulling the stroke.

Cursor

The cursor can be disabled by toggling the checkbox in the Cursor header.

Show Fill Color while Drawing

Shows the brush linked material color in the viewport.
