To have delegate speed considered for motion synthesis, turn on Use Speed, choose Range or Unique, and then make the appropriate settings.

Speed is measured in units per animation frame, where the unit is the current 3ds Max system unit. By default, this is Generic Units.
Interface
- Use Speed
-
Turn on to have the motion synthesis engine consider delegate velocity in determining whether to use the clip.
Range group
When you choose Range, the motion synthesis engine activates the clip when the delegate's speed falls inside the specified range.
- Min/Avg Max display
-
After you synthesize the Master Motion Clips, displays delegates' minimum, average, and maximum speed.
- Min
-
Set the minimum speed value for the range.
- Max
-
Set the maximum speed value for the range.
Unique group
When you choose Unique, the motion synthesis engine activates the clip when the delegate's speed matches a specific value, optionally with a rising, falling, or constant value before or after the specified value.
- Value
-
Set a unique speed value.
- In and Out groups
-
These radio buttons let you specify the behavior of the parameter before and after the unique value is met. For example, with a flying object, to trigger a landing animation clip you might set the unique value to 0, the In setting to Decreasing, and the Out setting to Constant. This means that the object has slowed down and then stopped, and is now stationary.
- Anything Speed before or after the target value is not relevant.
- Decreasing Speed decreases before or after it reaches the target value.
- Constant Speed before or after the target value is constant.
- Increasing Speed increases before or after it reaches the target value.
Scale Playback Speed group
These settings let you scale the rate at which the animation is played depending upon the speed of the delegate. By default, when Scale Animation is off, the object animation will always play at its normal rate. If you turn it on, you can then set a Base Speed, at which the animation should play at its normal rate, plus a percentage to specify how much the animation rate is modified by the actual delegate speed.
- Scale Animation
-
Scales the clip's animation based on speed.
For example, as a bird increases its velocity, its wings beat more rapidly. Scaling an animation scales the keys of the animation.
- Percentage
-
Specify how much to alter the playback speed based upon the difference between the delegate's speed and the Base Speed setting.
The formula used is this:
Animation Speed change % = (current speed/Base Speed – 1) x Percentage %
For example, if a delegate is moving 50 percent faster than the base speed, and the Scale Percentage value is 50, then the playback speed is scaled up by 25 percent.
- Base Speed
-
Specifies the delegate speed at which the animation should be played back at its normal rate.
