Real Wet Oil controls

---

The Real Wet oils 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.

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

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 oils brushes interact with canvas texture and grain. For example, you can adjust the canvas roughness, which affects all other canvas settings.

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

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 choose a dab profile using the property bar.

To adjust the Real Wet Oil controls

 

To	Do the following
Set the amount of oil the brush deposits on the canvas	In the Brush area, move the Wetness slider to adjust the amount of liquid.
Set the concentration of paint the brush deposits on the canvas	In the Brush area, move the Concentration slider to adjust the amount of pigment.
Adjust the oil thickness to control the way it spreads on the surface of the canvas	In the Liquid Flow area, move the Viscosity slider to adjust the viscosity effect.
Adjust the speed at which the paint dries	In the Liquid Flow area, move the Evaporation Rate slider to adjust the effect.
Adjust the degree to which the flow map surface, or the paper texture, affects the direction of the water flow	In the Flow area, move the Flow Resistance slider to adjust the effect.
Adjust the opacity of the paint deposited on the canvas after the oil dries	In the Paint area, move the Settling Rate slider to the left to decrease the amount of paint (more opacity) or to the right to increase the amount of paint (less opacity).
Control how easily the paint colors mix on the canvas	In the Paint area, move the Blend Rate slider to the left to decrease the blending capacity or to the right to increase the blending capacity.
Specify the degree to which oil is able to lift dry paint from the canvas	In the Paint area, move the Pickup slider to adjust the amount of paint pickup.
Adjust the canvas roughness	In the Canvas area, move the Roughness slider to the left to decrease the canvas roughness or to the right to increase the canvas roughness. (This impacts flow resistance, dry rate, and paint granulation.)
Control the effect canvas grain has on the direction of the paint flow	In the Canvas area, move the Flow Resistance slider to adjust the flow resistance.
Adjust the rate at which the canvas grain can absorb paint	In the Canvas area, move the Dry Rate slider to adjust the speed of absorption.
Control the degree to which paint settles into the valleys of the canvas grain when it dries	In the Canvas area, move the Granulation slider to adjust the effect.
Control the angle at which paint spreads on the canvas	In the Wind area, move the Angle slider to adjust the angle.
Specify the amount of wind force exerted on paint, which affects the way it spreads on the canvas	In the Wind area, move the Force slider to adjust the force.

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.

To apply a flow map when using a Real Wet oils brush

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

 

To	Do the following
Apply diffusion precisely to ensure accurate water flow	Enable the Accurate Diffusion check box.
Delay diffusion until the brushstroke is complete	Enable the Delay Diffusion check box.
Suspend diffusion temporarily	Enable the Pause Diffusion check box to suspend the diffusion. You need to disable the check box to perform the diffusion.
Specify the speed at which the paint is revealed onscreen	Move the Animation Step slider to the left to lower the speed of the animation or to the right to increase the speed. Specifying a lower Animation Step, such as 0, produces a smoother effect.
