Real Wet Oil

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 Real Wet Oil 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)

Paint controls

The paint controls let you to 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.

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

You can also adjust the flow resistance to control how paint spreads on the canvas. 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.

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

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.


To	Do the following
Set the amount of oil the brush deposits on the canvas	In the Brush area, move the Wetness slider to the left to decrease the amount of liquid or to the right to increase the amount of liquid.
Set the concentration of paint the brush deposits on the canvas	In the Brush area, move the Concentration slider to the left to decrease the amount of paint or to the right to increase the amount of paint.
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 the left to decrease the viscosity effect or to the right to increase the viscosity.
Adjust the speed at which the paint dries	In the Liquid Flow area, move the Evaporation Rate slider to the left to decrease the evaporation effect or to the right to increase 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 the left to decrease the amount of paint pickup or to the right to increase 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 the left to decrease the resistance or to the right to increase the resistance.
Adjust the rate at which the canvas grain can absorb paint	In the Canvas area, move the Dry Rate slider to the left to decrease the speed of absorption or to the right to increase 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 the left to decrease the effect or to the right to increase the effect.
Control the angle at which paint spreads on the canvas	In the Wind area, move the Angle slider to the left to decrease the angle or to the right to increase 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 the left to decrease the force or to the right to increase the force.


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.
