Eraser Tool Properties

The Preview area lets you see a preview of the stroke your drawing tool will make.

The arrow button right of the display area opens the Eraser Properties dialog, which gives you access to all the parameters and options for your eraser. The Tool Properties view only gives you access to a few of the eraser properties, a list of eraser presets and options for the Eraser tool that are not related to the eraser properties. For more information on the Eraser Properties dialog, see the Eraser Properties Dialog section below.

By default, Harmony has preloaded eraser presets. You can also create your own eraser presets by configuring your eraser, then saving its properties into a new preset. It is also possible to export and import eraser presets.

Creates a new preset based on the current tool properties.

Deletes the currently selected preset.

Allows you to rename the currently selected preset.

Allows you to import brush presets exported from Harmony.

Allows you to export your brush presets into an .xml file.

This is where you select the shape of the eraser tip. By default, it is round.

The minimum and maximum sizes of your drawing tool produce the thick and thin effect on your stroke. This works with the pressure sensitivity of a pen tablet.

• Maximum Size: Defines the maximum width of the stroke.
• Minimum Size: Defines the minimum width of the stroke in relation to and as a percentage of the maximum size.

You can control the size properties by clicking on the arrow button on right and the dialog box will appear as shown below.

• Pressure: Allows you to apply more pressure and increases the size of the brush. You can check the box to invert this behaviour.
• Tilt: Allows you to tilt the pen closer to tablet for a bigger stroke. You can check the box to invert this behaviour.
• Speed: Allows you to reduce the size of the stroke by drawing at a fast speed. You can check the box to invert this behaviour.
• Speed Sensitivity: A slider is used to control how fast must the stroke be drawn to reach the minimum value.
• Taper: Allows you to reduce the value of a property at the start or the end of each stroke. The value can be expressed using two options: Distance and Percentage. Distance is selected by default. For example: A taper of 200 will be the same length as the width (diameter) of a stroke that has its size set at 200.

You can enable Start and End Tapering option individually.

• Start Taper: When distance is selected as a Taper value, the effect of start taper can be visualized as the stroke is drawn.
• End Taper: When distance or percentage is selected as a Taper value, the effect of end taper can be visualized once the stroke is complete and vectorized as the length is unknown until the stroke is complete.

• Fade Distance: Allows you to fade the value of property over a given distance. It uses the same units as the size and is applied as the stroke is drawn.

If you check this option, the size of the eraser will be adjusted to the position of the camera on the z-axis. This means that if the camera is zoomed in on the scene, the eraser will be proportionally smaller so that it appears the same size in the rendered image. Likewise, if the camera is zoomed out, the eraser will be proportionally bigger.

The Roundness and Angle parameters allow you to change the shape and orientation of the tip.

• Roundness: The vertical scaling to apply to the tip. Reducing this setting squashes the tip vertically, allowing you to turn round or square tips into flat tips.
• Angle: The angle at which to rotate the brush tip, counterclockwise.

If your pen and tablet support tilt sensitivity, this option allows you to set whether your eraser takes your pen's tilt angle in account, and how much.

When your pen is fully tilted, your eraser tip will be stretched by the percentage you set in this parameter, in the angle in which you tilt it. For example, if you set the Pen Tilt Sensitivity to 50%, and you tilt your pen all the way up or down, your eraser tip will be stretched vertically by 50%. With the same setting, if you tilt your pen all the way left or right, your eraser tip will be stretched horizontally by 50%.
