After closing a new shape, you will switch to the Reshape tool automatically.

Sets the default blur type: Center, Inner, Outer.

Sets the size of control point handles.

Sets the default keyframe interpolation type.

There is no interpolation and abrupt switches in value occur at keyframes.

When values change, a straight line with sharp, abrupt angles from one keyframe to the next is drawn.

Eases in to the selected keyframe.

Eases out of the selected keyframe.

Eases in and out of a selected keyframe.

Smooth (Catmull-Rom) creates a smooth curve between keyframes.

Sets the default mode for the Reshape tool.

Selected points all move the same amount.

Points near the cursor move more than points farther away.

Uses a circular brush to automatically select and then move points when you click and drag them using the Magnetic Reshape behavior.

Enables the Silhouette v5 and below Feather tool. Once enabled, the Feather tool appears in the user interface.

Go to Appendix E - Legacy Feather to see how it works.

Draws unselected/inactive shape outlines using the shape opacity value. Alternatively, the V key toggles the Fade Outline with Opacity behavior.

When enabled, point selection is done by freehand selection. Press Ctrl while dragging for rectangular selection.

When disabled, point selection is done by rectangular selection. Press Ctrl while dragging for freehand selection.

When activated, tangents/hulls hide when editing.

When activated, the shape outline is hidden when editing.

Enables all interpolation types except for Smooth (Catmull-Rom).

Interpolation types are limited to Smooth (Catmull-Rom), Hold and Extrapolate. This ensures that shapes using Smooth (Catmull-Rom) interpolation in Silhouette exactly match the result in Nuke when exported.

Control points are not numbered.

Only control points that have been tagged using the Reshape tool > control point pop-up menu are numbered.

All control points are numbered.

Sets what shape type is used when circles and squares are created.

Bézier shapes are used for circle and square creation.

B-Splines are used for circle and square creation.

X-Splines are used for circle and square creation.

Drastically improves the curvature of shapes and reduces artifacts when using feathering. You can return to the previous behavior of v4.0.4 and below which used a fixed-step iterator by turning this preference off, if for some reason it causes shape artifacts.

Controls whether the automatic anchor point is set to the center of the collective bounding box or to the opposite handle.

Displays feather handles on shape points. Shift-F toggles this setting.

Displays the shape name in the center of the shape.

Turns Bézier tangents on or off. Turns B-Spline and X-Spline hull drawing on or off.

Controls whether the automatic anchor point is set to the center of the collective bounding box or to the opposite handle.

Controls the default weighting of X-Spline points when they are created.

X-Spline points have B-Spline weighting.

X-Spline points have Cardinal weighting.

X-Spline points have Corner weighting.

This is a weight from -10 to 10 that is multiplied by the mouse delta when manipulating the X-Spline point tension. You can reverse the sense of the weight by making this value negative. Also, you can boost the amount the tension is adjusted based on mouse movement by making the value larger, for example closer to -10 or 10.
