Synopsis

scaleKey( objects , [animation=string], [attribute=string], [autoSnap=boolean], [controlPoints=boolean], [float=floatrange], [floatPivot=float], [floatScale=float], [hierarchy=string], [includeUpperBound=boolean], [index=uint], [newEndFloat=float], [newEndTime=time], [newStartFloat=float], [newStartTime=time], [scaleSpecifiedKeys=boolean], [shape=boolean], [time=timerange], [timePivot=time], [timeScale=float], [valuePivot=float], [valueScale=float])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

scaleKey is undoable, NOT queryable, and NOT editable.

This command operates on a keyset. A keyset is defined as a group of keys within a specified time range on one or more animation curves.

The animation curves comprising a keyset depend on the value of the "-animation" flag:

Note that the "-animation" flag can be used to override the curves uniquely identified by the multi-use "-attribute" flag, which takes an argument of the form attributeName, such as "translateX".

Keys on animation curves are identified by either their time values or their indices. Times and indices can be given individually or as part of a list or range (see Examples).

This command takes keyframes at (or within) the specified times (or time ranges) and scales them. If no times are specified, the scale is applied to active keyframes or (if no keys are active) all keys of active objects.

This command has two sets of flags for scaling in time/x-axis. One set of flags is for time-based animation curves, and the other set of flags is for float-based (unitless) animation curves. Most animation curves in Maya are time-based. Unitless animation curves are less common. Use the set of flags that corresponds to the type of animation curves being scaled.

To scale all selected animation curves regardless of their type, use both sets of flags.

Return value

Flags

animation, attribute, autoSnap, controlPoints, float, floatPivot, floatScale, hierarchy, includeUpperBound, index, newEndFloat, newEndTime, newStartFloat, newStartTime, scaleSpecifiedKeys, shape, time, timePivot, timeScale, valuePivot, valueScale
Long name (short name) Argument types Properties
animation(an) string create
Where this command should get the animation to act on. Valid values are "objects," "keys," and "keysOrObjects" Default: "keysOrObjects." (See Description for details.)
attribute(at) string createmultiuse
List of attributes to select

In query mode, this flag needs a value.

autoSnap(asp) boolean create
Auto snap scaled keys if True. Default value depend on scaleKeyAutoSnap option
controlPoints(cp) boolean create
This flag explicitly specifies whether or not to include the control points of a shape (see "-s" flag) in the list of attributes. Default: false. (Not valid for "pasteKey" cmd.)

In query mode, this flag needs a value.

float(f) floatrange createmultiuse
value uniquely representing a non-time-based key (or key range) on a time-based animCurve. Valid floatRange include single values (-f 10) or a string with a lower and upper bound, separated by a colon (-f "10:20")

In query mode, this flag needs a value.

floatPivot(fp) float create
Scale pivot along the x-axis for float-based (unitless) animCurves
floatScale(fs) float create
Amount to scale along the x-axis for float-based (unitless) animation curves animCurves
hierarchy(hi) string create
Hierarchy expansion options. Valid values are "above," "below," "both," and "none." (Not valid for "pasteKey" cmd.)

In query mode, this flag needs a value.

includeUpperBound(iub) boolean create
When the -t/time or -f/float flags represent a range of keys, this flag determines whether the keys at the upper bound of the range are included in the keyset. Default value: true. This flag is only valid when the argument to the -t/time flag is a time range with a lower and upper bound. (When used with the "pasteKey" command, this flag refers only to the time range of the target curve that is replaced, when using options such as "replace," "fitReplace," or "scaleReplace." This flag has no effect on the curve pasted from the clipboard.)
index(index) uint createmultiuse
index of a key on an animCurve

In query mode, this flag needs a value.

newEndFloat(nef) float create
The end of the float range to which the float-based (unitless) animation curves should be scaled.
newEndTime(net) time create
The end of the time range to which the time-based animation curves should be scaled.
newStartFloat(nsf) float create
The start of the float range to which the float-based (unitless) animation curves should be scaled.
newStartTime(nst) time create
The start of the time range to which the time-based animation curves should be scaled.
scaleSpecifiedKeys(ssk) boolean create
Determines if only the specified keys are affected by the scale. If false, other keys may be adjusted with the scale. The default is true.
shape(s) boolean create
Consider attributes of shapes below transforms as well, except "controlPoints". Default: true. (Not valid for "pasteKey" cmd.)

In query mode, this flag needs a value.

time(t) timerange createmultiuse
time uniquely representing a key (or key range) on a time-based animCurve. See the code examples below on how to format for a single frame or frame ranges.

In query mode, this flag needs a value.

timePivot(tp) time create
Scale pivot along the time-axis for time-based animation curves
timeScale(ts) float create
Amount to scale along the time-axis for time-based animation curves
valuePivot(vp) float create
Scale pivot along the value-axis
valueScale(vs) float create
Amount of scale along the value-axis

Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.

Python examples

import maya.cmds as cmds

# Keys on animation curves are identified by either
# their time values or their indices.  Times and indices can
# be given as a range or list of ranges.

# time=('10pal','10pal') means the key at frame 10 (PAL format).
# time=[('1.0sec','1.0sec'),('15ntsc','15ntsc'),(20,20)] means the keys at time 1.0 second, frame 15 (in NTSC format), and time 20 (in the currently defined global time unit).
# time=(10,20) means all keys in the range from 10 to 20, inclusive, in the current time unit.
# Omitting one end of a range means "go to infinity", as in the following examples:
# time=(10,None) means all keys from time 10 (in the current time unit) onwards.
# time=(10,) means the same as (10,10)
# time=(0,10) means all keys up to (and including) time 10 (in the current time unit).
# time=(None,None) is a short form to specify all keys.
# index=(0,0) means the first key of each animation curve. (Indices are 0-based.)
# index=[(2,2),(5,5),(7,7)] means the 3rd, 6th, and 8th keys.
# index=(1,5) means the 2nd, 3rd, 4th, 5th, and 6th keys of each animation curve.

# Scale keyframes from frame 10 to 20 of nurbsSphere1's translateX
# to fill frames 10 to 30.
#

# Scale all the animation of the active objects
# (range 0-30) to fill range 0 to 60.
