Vertex Painting

Vertex Painting is a simple way of painting color onto an object, by directly manipulating the color of vertices, rather than textures, and is fairly straightforward.

When a vertex is painted, the colour of the vertex is modified according to the rules of the 'brush'. The color of all visible planes and edges attached to the vertex are then modified with a gradient to the color of the other connected vertices. (Note that the color of non-visible faces are not modified).

Vertex colors can be painted by switching to Vertex Paint Mode, however, it will not show up in the render unless you check "Vertex Color Paint in the Materials Options Panel.

Settings

The Tools Shelf, shortcut T contains most of the options for vertex painting.

Brush

The image at the top allows you to select tool presets, rename brushes, as well as add custom brushes, and delete them.

Radius

Set the radius of the brush

Strength

Set the strength of the brush's effect.

Tool

Mix

Mixes RGB values. When set to a strength of 1.0, it will cover the underlying "paint".

Mix overlay with full strength

Add

Adds RGB values. Will eventually turn the entire object white as RGB values accumulate to 1.0-1.0-1.0: Pure White.

Subtract

Subtracts RGB values. Usually results in Black.

Subtract with full strength

Multiply

Multiplies brush colors by the vertex colors.

Blur

Blurs vertex colors.

Lighten

Lightens the color of the vertices.

Darken

Darkens the color of the vertices.

Stroke

Airbrush

Flow of the brush continues as long as the mouse click is held, determined by the Rate setting. If disabled, the brush only modifies the color when the brush changes its location.

Smooth stroke

Brush lags behind mouse and follows a smoother path. When enabled, the following become active:

Radius

Sets the minimun distance from the last point before stroke continues.

Factor

Sets the amount of smoothing.

Space

Creates brush stroke as a series of dots, whose spacing is determined by the Spacing setting. Spacing represents the percentage of the brush diameter.

Curves

Brush Curves affect how strongly the color is applied depending on distance from the center of the brush. In other words, they allow you to edit the Falloff of the brush intensity.

Appearance

Allows you to customize the color of the brush radius outline, as well as specify a custom icon.

Options

All Faces

Paints all faces inside the Brush radius. With it off, only the face that's at the center of the brush will be colored.

Normals

Applies the Vertex Normal before painting. This does not usually affect painting.

Spray

Has bug! Continues painting for as long as the mouse is held.

Unified Settings

Size

All brushes use the same size.

Strength

All brushes use the same strength.
