Real Wet Oil controls

The Real Wet Oil brush variants help you achieve realistic oil brushstrokes. For example, you can control paint viscosity and color concentration, similar to mixing oil paint and a medium. The following section describes the Real Wet Oil brush controls in more detail.

Brush controls

The Real Wet Oil brush-specific controls let you set the amount of liquid and paint that the brush deposits on the canvas.

Brushstrokes set at a lower Wetness setting (left) and higher Wetness setting (right)

Liquid Flow controls

The Liquid Flow controls let you adjust the liquid viscosity, or thickness, in order to control the way it’s applied to the canvas. For example, if the liquid viscosity is high, the paint spreads easily and looks smooth. If the liquid viscosity is low and thick, the paint does not spread as easily and creates the illusion of texture.

You can also adjust the speed at which the liquid evaporates, which influences how the paint dries on the canvas.

Brushstrokes set at a lower Evaporation Rate (left) and higher Evaporation Rate (right)

Flow controls

The Flow controls let you enable and choose flow maps, so you can introduce an additional surface texture to promote greater liquid displacement. For more information, see Getting started with flow maps. You can also adjust the flow resistance to control how paint spreads on the canvas or flow map.

Brushstrokes set at a lower Flow Resistance setting (left) and higher Flow Resistance setting (right)

Paint controls

The Paint controls let you modify the look and feel of paint on the canvas. For example, you can adjust the opacity of the paint deposited on the canvas after the oil dries. You can also specify how easily the paint blends and the degree to which oil is able to lift dry paint from the canvas.

Brushstrokes set at a lower Settling Rate (left) and higher Settling Rate (right)

Canvas controls

With the canvas controls, you can adjust how the Real Wet Oil brushes interact with canvas texture and grain. For example, you can adjust the canvas roughness, which affects all other canvas settings.

In addition, you can set the rate at which the paper grain can absorb liquid and control the amount of paint that settles into the valleys of the canvas grain when it dries.

Wind controls

The Wind controls let you to set the angle at which the paint spreads on the canvas. You can also specify the amount of wind force exerted on the paint.

Brushstrokes set at a lower Angle and Force settings (left) and higher Angle and Force settings (right)

Diffusion controls

The Diffusion controls allow you to manage how and when the paint is diffused on the canvas. You can specify that diffusion be precisely applied to ensure accurate paint dispersion. You can also delay diffusion so the effect is applied only after you complete a brushstroke. In addition, you can choose to suspend diffusion temporarily. This lets you apply multiple brushstrokes to the canvas before applying the diffusion, to apply the effect to all brushstrokes at once. You can also specify the number of flow steps to be completed during animation. This controls the rate at which the visual flow of the paint refreshes onscreen. For example, you can specify a lower number of steps for smaller brushes and a higher number of steps for bigger brushes.

You can set some Real Wet Oil options on the property bar. For more information, see To set brush options on the extended property bar.

To adjust the Real Wet Oil controls

1	Choose Window Brush Control Panels Real Wet Oil.

You can improve the appearance of the visual flow of paint onscreen by clicking the Magnifier tool in the toolbox, and disabling the High Quality Display button on the property bar.

2	Choose Window Brush Control Panels Real Wet Oil.

To maximize the effect of flow maps, you need to ensure that the Wetness control is set high and the Evaporation Rate control is set low.

To control Real Wet Oil diffusion

1	Choose Window Brush Control Panels Real Wet Oil.
