Shape
Auto Switch to Reshape Tool
After closing a new shape, you will switch to the Reshape tool automatically.
Blur Type
Sets the default blur type: Center, Inner, Outer.
Control Handle Size
Sets the size of control point handles.
Default Interpolation
Sets the default keyframe interpolation type.
Hold
There is no interpolation and abrupt switches in value occur at keyframes.
Linear
When values change, a straight line with sharp, abrupt angles from one keyframe to the next is drawn.
Ease In
Eases in to the selected keyframe.
Ease Out
Eases out of the selected keyframe.
Ease In/Out
Eases in and out of a selected keyframe.
Smooth (Catmull-Rom)
Smooth (Catmull-Rom) creates a smooth curve between keyframes.
Default Reshape Tool
Sets the default mode for the Reshape tool.
Normal
Selected points all move the same amount.
Magnetic
Points near the cursor move more than points farther away.
Brush
Uses a circular brush to automatically select and then move points when you click and drag them using the Magnetic Reshape behavior.
Enable Legacy Feathering
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.
Fade Outline with Opacity
Draws unselected/inactive shape outlines using the shape opacity value. Alternatively, the V key toggles the Fade Outline with Opacity behavior.
Freehand Point Selection
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.
Hide Hulls During Edit
When activated, tangents/hulls hide when editing.
Hide Outlines During Edit
When activated, the shape outline is hidden when editing.
Interpolation Engine
Temporal
Enables all interpolation types except for Smooth (Catmull-Rom).
Spatial (Nuke-compatible)
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.
Number Points
None
Control points are not numbered.
Tagged
Only control points that have been tagged using the Reshape tool > control point pop-up menu are numbered.
All
All control points are numbered.
Primitive Type
Sets what shape type is used when circles and squares are created.
Bézier
Bézier shapes are used for circle and square creation.
B-Spline
B-Splines are used for circle and square creation.
X-Spline
X-Splines are used for circle and square creation.
Recursive Subdivide
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.
Rotate from Center of Selection Bounding Box
Controls whether the automatic anchor point is set to the center of the collective bounding box or to the opposite handle.
Show Feather Handles
Displays feather handles on shape points. Shift-F toggles this setting.
Show Shape Name
Displays the shape name in the center of the shape.
Show Tangent Vectors
Turns Bézier tangents on or off. Turns B-Spline and X-Spline hull drawing on or off.
Transform from Center of Selection Bounding Box
Controls whether the automatic anchor point is set to the center of the collective bounding box or to the opposite handle.
X-Spline Point Type
Controls the default weighting of X-Spline points when they are created.
B-Spline
X-Spline points have B-Spline weighting.
Cardinal
X-Spline points have Cardinal weighting.
Corner
X-Spline points have Corner weighting.
X-Spline Tension Factor
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.
