These options let you set the default style, interpolation, and slope modes for function curves when they are created. There
are also options for setting the default autokey and keying behaviors, as well as keying in property editors.
To set preferences when editing function curves in the animation editor, see the Fcurve Editor Preferences property editor.
To display: Choose from the main menu. In the explorer that appears, click or its icon.
Autokey
These options apply to automatic keying. Automatic keying (autokeying) sets a key whenever you change a parameter's value.
This means that you don't have to click the keyframe button each time you change a value at a different frame.
For more information, see Setting Keys Automatically.
|
Activates the autokey feature. Autokey registers the parameter values you enter for the selected frame. You can also activate the autokey feature by clicking the button in the Animation panel, which is in lower-right corner of the main window. The auto button changes color when activated.
Select one of these options to determine the autokey behavior:
|
|
-
Sets a key whenever you change any properties.
When you autokey with this option, the auto button turns red.
|
|
-
Generates a new key when a parameter is changed only if there's already a key for that parameter at the current frame. This
makes it easy and safe for editing existing keys, allowing you to work in a mode similar to traditional animation.
When you autokey with this option, the auto button turns light orange.
|
|
-
Generates a new key when a parameter is changed only if the parameter already has an fcurve. New keys are added regardless
of whether or not there's already a key at the current frame.
When you autokey with this option, the auto button turns dark orange.
|
|
Sets keys only on modified parameters that already have fcurves instead of setting keys on all parameters. This is on by default.
|
|
When the is selected, this option displays a colored border around the viewport in which you click the mouse, as well as around the
timeline.
|
|
If the option is selected, you can select the highlight color. Click the color chip and select a color from the color editor.
|
Save Key
Determines which parameters are keyed when you save a key by pressing , by clicking the keyframe icon in the Animation panel or the keying panel, or by choosing the command from the Animation menu or Character Key Set menu.
These options do not affect keying by using a parameter's animation icon.
For more information, see Selecting Which Keying Method to Use.
|
-
sets keys only on marked parameters. This is the default method for working in Softimage.
For more information, see Keying Marked Parameters.
-
sets keys on all parameters that are displayed in the keying panel for the selected object. These parameters are known as
keyable parameters.
If you're using the Maya or 3ds Max interaction mode, this option is on by default.
For more information, see Keying Keyable Parameters in the Keying Panel.
-
sets keys only on keyable parameters that you have marked in the keying panel. This is mixture that lets you set keys on
the intersection of parameters that are both keyable and marked.
-
Set sets keys only on parameters in the current character (or subcharacter) key set.
For more information, see Keying with Character Key Sets.
|
|
Sets keys only on modified parameters that already have fcurves instead of setting keys on all parameters. This is off by
default.
|
Curves
For more information, see Editing a Function Curve's Slope.
|
These options determine the curve style when function curves are created.
-
Sets the default function curve style to the Softimage style (default), where function curves are drawn with slope handles
(tangents) whose length can be changed.
-
Sets the default function curve style to be the same as in SOFTIMAGE|3D, where the function curve slope handles remain a
fixed length. You can also convert existing function curves to this style with the command in the fcurve editor.
For more information, see Editing a Function Curve's Slope.
|
Keys
|
Determines which settings are used when adding keys to function curves.
-
Uses the fcurve's preference settings that were in effect when the fcurve was created or the last time a key was saved.
-
Uses the current preference settings as defined in this preferences property editor.
|
|
Determines the interpolation between key points (keyframes) on function curves. For more information, see Choosing a Function Curve Interpolation Type.
-
Sets the interpolation of an inserted key automatically to the same interpolation as the neighboring keys.
-
(Constant) Repeats the value of a key point until the next one. The movement is characterized by sudden changes at key points
and static positions between key points.
-
Connects key points by straight line segments. The movement is constant (no acceleration or deceleration) with sudden changes
at each key point.
-
Results in a smooth transition. Spline interpolation accelerates and decelerates to ease into and out of each key point.
The degree of acceleration and deceleration before and after the key point is determined by the tangent handles associated
with the key point.
|
|
Determines the default slope of function curves when they are created. For more information on slopes, see Editing a Function Curve's Slope.
-
Sets the slope of an inserted key automatically using the slopes of neighboring keys. Does not affect the slope of these
neighboring keys.
-
Sets the slope of an inserted key automatically to the slopes of neighboring keys using a combination of the Automatic and
Plateau Slope commands. It computes the orientation and length of a key's slope based on the interpolation of the fcurve between
the previous key and the next key (neighboring keys) in a plateau-type manner where the slopes gradually flatten out as they
approach their local maxima/minima. This mode affects the slope of the neighboring keys.
-
Sets the slope of an inserted key automatically to the slopes of its neighboring keys, without the plateau influence. This
option has the behavior of the option from Softimage versions previous to v7.0.
|
|
Determines the default slope's orientation when the function curves are created. For more information, see Setting the Slope's Orientation (Angle).
-
The slope's orientation is free to be modified by you, and/or it will get automatically calculated based on neighboring keys.
-
Sets the slope of an inserted key automatically to 0 if the next key has the same value or if that key is a local minimum
or maximum. A local minimum/maximum is a key point where both previous and next keys have either smaller (maximum) or larger
(minimum) values. This is useful to hold key-point values to prevent the automatic interpolation from going above of below
your keyed values.
-
Constrains the slope at key points to 0. The slope handles remain horizontal so that only the slope tension can be modified.
|
|
These options determine the default slope's handle (tangent) length when the function curves are created. For more information, see Controlling the Length of the Slope Handles.
-
The slope's length is free to be modified by you, and/or it will get automatically calculated based on neighboring keys.
-
Creates sharp points (break points) on the curve, allowing you to manipulate the handles independently.
-
Keeps the length for the slope handles equal on both sides of the key point.
|
|
These options determine how the resulting fcurves are created when you collapse animation layers. For more information, see Collapsing or Storing the Animation Layers.
-
The tangent handles of the resulting collapsed fcurves are altered in order to preserve the object's animation.
-
The tangent handles of the resulting collapsed fcurves are preserved. This may alter the object's resulting animation.
|
Animation Scope in Editors
This applies only to the keyframe icon (set key) at the top of property editors. It has no effect on the keyframe icon on
the Animation panel or the keying panel, the Save Key command in the Animation menu, nor on the K key.
For more information, see Keying Parameters in Property Editors.
|
If a property set is keyed, this option applies the changed values to all parameters if no individual parameters are marked.
This option is on by default, meaning that all parameters in a property editor are keyed if nothing is marked.
|
Timing for New Scene
|
Sets the start/end frame for the time range when you create a new scene.
|
Fr. Rate change: keep fcurve timings fixed
Allows function curves to maintain their keyframes at the original frame values when the frame rate is changed.
|
The values of the keys at the current frame appear to change.
|
|
The fcurves are scaled to compensate for the change in frame rate.
