Using UV Brush

  1. Select your model.

  2. Click the UV Brush tool on the Texture tab.

  3. Drag the brush tool over the UVs to move them.

For general brush information see the Brush tool help.

Parameters

Operation

Operation

The operation used by Apply To All.

Drag

This will drag the points along the brush direction.

Dilate/Contract

This will move points towards or away from the center of the brush according to the scale (either FS or BS).

Smooth

This will smooth out the texture coordinates under the brush. Boundary points will be preserved.

Erase Changes

This will perform a local undo under the brush.

Reset All Changes

This button will restore the geometry to its original state.

Foreground/Background

The dilation/contraction factors used for foreground and background modes. The left mouse will use the FS scale factor and the middle mouse the BS scale factor.

Apply To All

Paints all of the selected geometry.

Reset All Changes

Restores geometry to initial state.
Brush

Shape

The basic shape of the brush: circle, square, or bitmap.

Bitmap

What bitmap to use. The alpha channel becomes the brush.

Radius

The radius of the brush when painting in the 3d viewport.

UV Radius

The radius of the brush when painting in the 2d viewport.

Radius Pressure

This controls how much effect the pressure of a stylus will have on the radius. A value of 1 means the radius will go from 0 to the amount in Radius. A value of 0 will mean the radius will always be constant, regardless of pressure. A value of 0.5 will mean the radius will be scaled between one half of Radius and Radius.

Depth

If set, this limits how far the brush will paint along its axis. This can be used if connectivity is disabled to limit the effect of the brush. The first parameter is how deep below the surface the brush should penetrate. The second is how high above the surface it should stop. These values can be negative.

Brush Angle

How far to rotate the brush.

Brush Squash

Amount to squash the brush in the y direction before rotation.

Opacity

The amount to affect the stencil mask.

Opacity Pressure

This controls the how much effect the pressure of a stylus will have on the opacity. It obeys the same scaling as the Radius Pressure.

Brush Splatter

A random noise in the brush’s opacity based upon the position on the brush.

Paper Grain

A random noise on the object’s stencil mask based on the object position.

Soft Edge

Percentage of the brush to be rolled off.

Kernel Function

Which metaball kernel to use for the roll off.

Up Vector Type

How the brush should be oriented on the surface:

Stroke Direction

Oriented in the direction in which the brush moves.

Fixed

Oriented as specified in the Up Vector field.

Up Vector

The fixed up vector to orient brush to.
