These Options are the same as those you will find in the Apint Room and offer you comprehensive control over your Brush behavior.
At the top of the panel is a preview of the Brush Alpha shape followed by a series of behavior controls.

Brush rotation: This sets the initial orientation of the alpha at the beginning of the stroke.
Zero pressure radius: When using a tablet stylus, this number indicates the default radius at the beginning of the brush stroke.
Depth modulator: The default depth for each brush being used.
Rotation amplitude: Sets the amplitude for additional brush rotation.
Radius variation: Sets the percentage of random brush radius variation.
Depth variation: Sets the percentage of random brush depth.
Opacity jitter: Defines the randomness of the brush opacity setting.
Jitter: The overall randomness of brush behavior.
Hue jitter: Defines the randomness of the brush hue when used for painting color.
Brightness jitter: Varies the brightness, randomly, over the course of a stroke.
Saturation jitter: Varies the saturation of the primary color, randomly, over the course of the stroke.
Vary color each stroke: Use this option to produce painting effects, like fur or hair, when you need to either vary the Hue/Saturation/Brightness as you paint a single stroke, (variegated strand color), or when you want each stroke made to have a slightly different Hue/Saturation/Brightness - as determined by the corresponding “Jitter” setting.
Random flip (x, y): This randomly flips the selected brush either across its x or y axis while painting.
Paint with dabs: Creates paint or sculpting “dabs” which occur at some set spacing - as determined by the “Spacing” control.
Rotate along stroke: When using brush alpha shapes that you want to align like the bristles of a brush - so that they change direction as the brush changes direction, all along the stroke use this option.
Skip eraser: Disables the “eraser layer” of the brush.
Strict alpha: Use this setting to cause both sculpting and painting brushes to strictly adhere to the shape defined by the brush alpha.
Flattened stroke: Use this brush setting to mimic Photoshop brushes for improved stroke overlapping with a truncated alpha shape.
Fade on edge: All strokes painted with this option checked will have a smoother edge transition.
Use spacing: When used with the “Paint with dabs” option, adjusting the “Spacing” percentage slider determines how close or far apart the paint dabs are applied.

This new brush engine lets you modify controls for the sculpting tools. There are a wide variety of brushes and each one has a unique property.

To access Tool options you need to click Edit brush parameters.

This picture shows the new Brush Tool Options Panel

This option is not supported if Modify connected is enabled. Uncheck “Modify connected”

Alphas: The Alpha controls the shape of the brush. An alpha is a grayscale intensity map.
There are 2 selection methods, use what already exists in the alpha library or procedurally create new ones using the curve editor.
Switch on Use current alpha to access to the library of alphas (T hotkey).

Switch off to use new procedural alphas.
