Vertex Painting Mode

From BlenderWiki

Vertex PaintingVertex 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 ofall visible planes and edges attached to the vertex are then modified with a gradient to the color of the otherconnected vertices. (Note that the color of non-visible faces are not modified).

Vertex colors can be painted by first going into Edit Mode, then switching to Vertex Paint Mode; however, itwill not show up in the render unless you check "Vertex Color Paint" in the Materials Options Panel.

SettingsThe Tools Shelf, shortcut T contains most of the options for vertex painting. The following sections describe thecontrols in each of the available panels.

Brush

Brush DatablockThe image, name panel and color selector at the top allows you to select brush presets, rename brushes,as well as add custom brushes, and delete them.

RadiusSet the radius of the brush

StrengthSet the strength of the brush's effect.

Blend menu

Page 2: Blender Materials - Vertex Painting

Mix overlay with full strength

Subtract with full strength

MixMixes RGB values. When set to a strength of 1.0, it will cover theunderlying "paint".

AddAdds RGB values. Will eventually turn the entire object white as RGBvalues accumulate to 1.0-1.0-1.0: Pure White.SubtractSubtracts RGB values. Usually results in Black.

MultiplyMultiplies brush colors by the vertex colors.BlurBlurs vertex colors.LightenLightens the color of the vertices.DarkenDarkens the color of the vertices.

Stroke

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

Smooth strokeBrush lags behind mouse and follows a smoother path. Whenenabled, the following become active:

RadiusSets the minimun distance from the last point before stroke continues.FactorSets the amount of smoothing.

SpaceCreates brush stroke as a series of dots, whose spacing is determinedby 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. Inother words, they allow you to edit the Falloff of the brush intensity.
