Brush settings.

With this panel, you can create many brushes, each with unique settings (such as color and width). In the UV/Image Editor this panel is called Paint.

Brush Types

Texture Draw

The normal brush, paints a swath of color. See Common settings below.

Use Gradient

A gradient can be used as a color source.

Gradient Colors

The Color Ramp Widget to define the gradient colors.

Mode
Pressure

Will choose a color from the color ramp according to the stylus pressure.

Clamp

Will alter the color along the stroke and as specified by Gradient spacing. With Clamp it uses the last color of the color ramp after the specified gradient.

Repeat

Similar to Clamp. After the last color it resets the color to the first color in the color ramp and repeats the pattern.

Fill

It can be used to fill large areas of the image with the brush color. The tool fills adjacent pixels that have a color value similar to the pixel you clicked on.

Fill Threshold (2D only)

Determines how much the color must be similar to the color of pixel you click to be filled. A low Threshold only fills very similar in color pixels. A higher Threshold fills pixels within a broader range of color.

Use Gradient

Allows the use of a gradient to fill the image.

To apply the gradient with the Fill brush click LMB and drag to define the gradient line, or radius if a radial gradient is used (depending on the Gradient Fill Mode).

Gradient Colors

The Color Ramp Widget to define the gradient colors.

Gradient Fill Mode

Linear, Radial

Note

Overrides

For projective texturing it will bypass some options for projective painting to paint the model. This means that occluded, backfacing and normal culled faces will always get filled, regardless of whether the options are activated in the Project Paint panel.

Mask

The mask feature maps an image to the mesh and uses the image intensity to mask out certain parts of the mesh out during painting. The mask options can be found in the mask panel’s slots tab. It’s only available for 3D projective painting.

Mask Value

Mask weight, a value of zero means not masked, while one is completely masked.

Soften

Uses a “blur effect” to soften or sharpen the image.

Direction
Soften

Is used to paint a blur effect.

Kernel Radius (2D only)

Blur radius in pixels.

Sharpen

The Sharpen tool enhances the contrast of the image as you paint over it.

Sharp Threshold

The Threshold will only apply sharpening to only those pixels that differ more than the threshold value from their surrounding pixels.

Kernel Radius (2D only)

The kernel size controls how big an area the tool searches over is while calculating that difference.

Blur Mode

The blur kernel type controls how neighboring pixels are weighted when calculating the blur effect.

Gaussian

Gaussian will sample the pixels near the center of the brush most.

Box

Box samples all surrounding pixels equally.

Smear

When you click, takes the colors under the cursor, and blends them in the direction you move the mouse. Similar to the “smudge” tool of Gimp.

Clone

Copies the colors from the specified image (or location of the same image) to the active image.

In 3D projective painting the clone cursor can be set with Ctrl-LMB. In 2D painting the clone can be moved dragging it with RMB.

Clone from Paint Slot (3D projective only)

Use another image as clone source, instead of using the 3D cursor position as the source in the same image.

Source Clone Slot

This allows you to select an image as a clone source.

Image (2D only)

Image used as a clone source.

Alpha (2D only)

Opacity of the clone image display.

Common

Most brushes have common settings.

Color

The color of the brush. See Color Picker.

Press S on any part of the image to sample that color and set it as the brush color. Hold Ctrl to paint with background color.

Flip (cycle icon) X

Swaps the foreground and background color.

Radius

The radius of the brush in pixels.

Strength

How powerful the brush is when applied.

Space Attenuation (padlock icon)

Attenuate the brush strength according to spacing.

Pressure Sensitivity (hand and bulged in blue line icon)

The toggle to the right of the following three settings will enable or disable tablet pressure sensitivity to control how strong the effect is.

Blend

Set the way the paint is applied over the underlying color. See Color Blend Modes.

  • Add Alpha: makes the image more opaque where painted.

  • Erase Alpha: makes the image transparent where painted, allowing background colors and lower-level textures to show through. As you “paint”, the false checkerboard background will be revealed. Using a table pen’s eraser end will toggle on this mode.

Tip

In order to see the effects of the Erase and Add Alpha mix modes in the UV/Image Editor, you must enable the alpha channel display by clicking the Display Alpha or the Alpha-Only button. Transparent (no alpha) areas will then show a checkered background.

Accumulate

This will allow a stroke to accumulate on itself, just like an airbrush would do.

Alpha (3D only)

When this is disabled, it locks (prevents changes to) the alpha channel while painting.

Tip

Masking

Use the face selection mask to isolate faces. See Face Selection Masking details.

Tilling

Wraps the stroke to the other side of the image as your brush moves off the opposite side of the canvas. Very handy for making seamless textures. (In the UV/Image Editor only.)
