Motion Blending 975
The purpose of the morph object in 3ds Max is to
create an animated object that changes shape by
morphing b etween two or more objects. Although
it appears that a single object is changing form,
in reality the morphing process translates the
position of the vertices from their arrangement in
one object to the arrangement in another, relative
to their local coordinate system.
Consequently, all objects chosen to make up a
morphobjectmusthavethesamenumberof
vertices. Typically, you achieve this by cloning
an object , and then altering the geometry of the
clones without changing their vertex count.

When working with motion flow (page 2–1026),
transitions are used to blend clips together. By
default, a transition is calculated with a method
known as “minimum motion loss.” If optimized
transitions are used, then a sophisticated algorithm
that minimizes foot sliding is used. This alternative
method is computationally expensive.
Motion Blur
Motion blur enhances the movement of the sword.
Motion blur can enhance the realism of a rendered
animation by simulating the way a real-world
camera works. A camera has a shutter speed, and
if significant movement occurs during the time the
shutter is open, the image on film is blurred.
3ds Max provides a variety of ways to apply motion
blur:
• Im age Motion Blur (page 3–955) applies motion
blur to entire frames of an animation.
• Motion Blur Rendering Effect (page 3–269) lets
you apply image motion blur as a rendering
effect (page 3–218).
• Multi-Pa ss Rendering Effect (page 2–1382)
applies motion blur to frames by offsetting the
camera in multiple rendering passes. You can
preview multi-pass rendering effects in camera
view por ts.
• Particle Motion Blur (page 2–240) uses a
material map to blur moving par t icles in a
particle system.
• Scene Motion Blur (page 3–1007) lets you apply
motion blur as a Video Post (page 3–311) effect.
• Object Motion Blur (page 3–981) applies
motion blur to specified mov ing objects in a
scene. Object mot ion blur is be st for ma king

Motion Clip
A motion clip is a sequence of motion on a biped
or other objects. A motion clip can be a BIP file, or
