Animation (Settings) preferences

 
 
 

You can set the following preferences in the Animation sub-category below the Settings category in the Preferences window. (There are also Animation preferences under the Display category. See Animation (Display) preferences.)

See also Edit animation preferences.

Auto Key

Auto key

Specifies whether Maya will automatically set keys on a previously animated object’s attributes when you change the values of those attributes. This preference has the same effect as the Animation Controls’ Auto Keyframe Toggle button (next to the Animation Preferences button in the Animation controls). This option is off by default.

On character sets

These options are available only when Auto Key is on.

For more information, see What are character sets?.

Key Modified Attributes

Sets keys only for attributes that have been modified.

Key All Attributes

Sets keys for all attributes, whether they have been modified or not.

Rotation Interpolation

To set the rotation interpolation options, see Set rotation interpolation for curves.

New curve default

Specifies the type of rotation interpolation used when creating curves. These options are the same as those available in the Change Rotation Interp menu item in the Graph Editor. For more information on rotation interpolation, see Animated rotation in Maya.

Independent Euler

Calculates the rotation using three separate angles representing rotations about the X, Y, and Z axes, and an order or rotation. In this mode, the curves that define the rotation for a given node are represented in Euler-angles, interpolation is performed on each curve independently in Euler space, and keyframes may occur at your discretion—they are not synchronized with the other sibling rotation curves at the node. You can also animate a single rotation ordinate. This is the default setting.

Synchronized Euler

Creates curves that have keyframes on sibling curves locked together but with interpolation between keyframes performed in Euler-space.

It’s useful to keep rotation keyframes synchronized because rotation is a composition of the three separate rotate values. Deleting just one key on a curve can have a dramatic and unexpected effect on the interpolation.

Quaternion Slerp

Interpolation is calculated using spherical linear interpolation and does not depend on the tangents of the input curves.

Quaternion Cubic

Interpolation is calculated using quaternion cubic interpolation (Squad) and does not depend on the tangents of the input curves.

Quaternion Tangent Dependent

Interpolation is calculated using quaternion interpolation based on the input curve tangents. For example, if the tangents are linear, Maya uses spherical linear interpolation (Slerp), and if the tangents are clamped, Maya uses cubic interpolation (Squad).

New HIK curve default

Let you set the default rotation interpolation type for new HIK curves. This drop-down list contains the same set of rotation interpolation options as the New curve default preference (listed above). The default for HIK curves is Quaternion Slerp.

Tangents

Tangents determine the status of curve segments when they enter and exit from a key.

Weighted tangents

Weighted tangents represent the amount of influence a tangent has on an animation curve segment. When on, all new tangents are automatically weighted. Weighted Tangents is off by default. See Edit tangents.

Default in tangent

Specifies the default in tangent type. The In Tangent setting controls the shape of the animation segment before a key.

Options include:

Auto

(Default) An Auto In Tangent compares the current keyframe value to the previous keyframe value, and flattens the curve segment if it travels above or below those keyframe values. (See also Auto tangents in the Graph Editor Tangents menu.)

Spline

A spline tangent rounds the animation curve smoothly before the key. If the key’s Out Tangent is also a spline, the tangents of the curve are then co-linear (both at the same angle). This ensures that the animation curve smoothly enters and exits the key.

Linear

A linear tangent creates an animation curve as a straight line before the key.

Clamped

The clamped tangent smoothly rounds the animation curve (like the Spline selection) before a key unless the next key is very close. If so, the In Tangent and the previous key’s Out Tangent are both straight (like the Linear selection), making the animation curve between the keys straight.

Flat

A flat tangent type sets the tangents before the key to be horizontal with a slope of 0 degrees (flat).

Plateau

A plateau tangent type eases animation curves in and out of their keyframes, flattens curve segments that occur between equal-valued keyframes, flattens keyframes at the points in their curves where hills and valleys occur, and flattens the first and last keyframes on their curves.

Default out tangent

Specifies the default out tangent type. The Out Tangent setting controls the shape of the animation curve right after a key.

Options include:

Auto

(Default) An Auto out tangent compares the current keyframe value to the next keyframe value, and flattens the curve segment if it travels above or below those keyframe values. (See also Auto tangents in the Graph Editor Tangents menu.)

Spline

A spline out tangent rounds the animation curve smoothly after the key. If the key’s In Tangent is also a spline, the tangents of the curve are then co-linear (both at the same angle). This ensures that the animation curve smoothly enters and exits a key.

Linear

A linear tangent creates an animation curve as a straight line after a key.

Clamped

Specifies the animation curve is smoothly rounded (like the Spline selection) after a key unless the next key is very close. If so, the Out tangent and the previous key’s In tangent are both straight (like the Linear selection), making the animation curve between the keys straight.

Flat

A flat tangent type sets the tangents after the key to be horizontal with a slope of 0 degrees (flat).

Stepped

A stepped tangent type forces the animation curve to hold its value from the one key to the next key.

Plateau

A plateau tangent type eases animation curves in and out of their keyframes, flattens curve segments that occur between equal-valued keyframes, flattens keyframes at the points in their curves where hills and valleys occur, and flattens the first and last keyframes on their curves.

Animation Blending

The Animation Blending preferences let you specify the types of blends that can occur between object connections. For example, when you turn on Always blend with existing connections, you can then both animate and constrain a single object.

Always blend with existing connections

When this preference is on:

  • You can move or key objects that have existing connections such as animation and constraints.
  • When you key or constrain an object, Maya inserts a pairBlend node between the object’s existing connections and the new keys or constraints.
  • The Lock Output attribute is off by default for all new constraints.

Always Blend with Existing Connections is on by default.

Blend with all except constraints

When this preference is on:

  • You can only key objects that are not constrained.
  • When you key an object, Maya inserts pairBlend nodes between the object’s existing connections and the new keys.
  • Objects with connections cannot be constrained.
  • The Lock Output attribute is on by default for all new constraints.

Never blend with existing connectionsi

When this preference is on:

  • You can only key objects that have no existing connections.
  • Maya does not insert pairBlend nodes to blend object connections.
  • The Lock Output attribute is on by default for all new constraints.

Graph Editor preferences

Snap Value to Adjacent Keys

When on (default), neighboring keys with similar values automatically align as you edit curves in the Graph Editor. Enable this preference if you want similar, adjacent keys to snap to identical values.

Left Mouse Button Alters Selections

When on (default), you can drag to move selected keyframes in the graph view area with a single click. When off, clicking selected keyframes has no effect in the graph view area, and you must select the Move tool and middle-drag to adjust keyframes. Enabling this option may be preferable if you are familiar with keyframe editing workflows in other Autodesk applications, such as MotionBuilder.

Camera Sequencer preferences

Shot Double Click

This preference lets you set what you want to occur when you double-click a camera shot in the Camera Sequencer.

Set Maya Frame Range

Set the frame range in the Time Slider to match the Maya start frame and Maya end frame of the selected shot. (See Camera shot overview.)

Select Camera

Select the camera assigned to the selected shot.

Frame Sequencer to Shot

Frame the selected shot in the shot view area.

Solo Track

Turn on the Solo option for the track containing the selected shot.

Don't Modify Sequence Time

Select to keep the Sequence Time indicator at the current time, regardless of where you double-click.

Set Sequence Time To Cursor

Select to have the Sequence Time indicator jump to where you double-click.

Set Sequence Time To Shot Start

Select to have the Sequence Time indicator jump to the start of the selected shot.
