1. What is the purpose of the mesh select
modifier?
• The mesh select modifier allows you to
create a sub-object selection so that you
can modify a portion of an object
independently without modifying the
entire object.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
2. Which type of material is used with the
material modifier?
• multi/sub-object
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
3. What is a displacement approximation
modifier used for?
• A displacement approximation modifier
is used in conjunction with displacement
mapping to deform the surface geometry
of a “non-mesh” object.

3DS MAX AND ITS APPLICATIONS
4. How does applying an edit patch modifier
to a parametric object differ from
converting the object into an editable patch
object?
• An object with an edit patch modifier is
not actually converted to an editable
patch, allowing the base object to
remain parametric.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
5. When is the normalized spline modifier
used?
• The normalize spline modifier is used to
space vertices equally along the length
of a spline, allowing the line to be used
as a motion path to generate a constant
velocity.

3DS MAX AND ITS APPLICATIONS
6. The surface modifier generates a patch grid
from what type of object?
• splines
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
7. Why would you use the delete mesh
modifier instead of deleting items at the
sub-object level?
• Using the modifier keeps the base object
parametric.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
8. What function does the tessellate modifier
perform?
• It subdivides faces on an object, which
allows you to add smoothness for
rendering.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
9. What effect can be created with the
displace modifier?
• A moving force field effect can be
created by applying the displace
modifier and animating the gizmo, or
using an animation as the bitmap.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
10. The lattice modifier produces what type of
object?
• wireframe
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
11. What does the push modifier do?
• The push modifier allows you to scale
an object up or down along the normals
of its faces.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
12. What do the xform and linked xform
modifiers allow you to do?
• The xform and linked xform modifiers
allow you to apply a transform to a
selection of sub-objects and place it in
the modifier stack.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
13. How does the xform modifier differ from
• When using the linked xform modifier,
the transform is controlled by the
transform of a control object.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
14. What does FFD stand for?
• Free Form Deformation
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
15. Which FFD modifiers allow you to set the
number of control points?
• FFD box
• FFD cylinder

3DS MAX AND ITS APPLICATIONS
16. If a melt modifier has a high solidity
value, what effect is produced on the
object?
• The object melts more on the outside
than the inside.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
17. What does the flex modifier do?
• It causes a portion of the object to “lag”
as the object is moved in an animation.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
18. With what is the skin modifier designed to
be used?
• bones systems
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
19. What is the main difference between
world space modifiers and object space
modifiers?
• The effects of a world space modifier are based on world
space rather than object space.
• The effects change as the object is moved around in the
scene, even if the object’s parameters remain unchanged.
• The effects of an object space modifier are dependent on
object space only.
• The effects of an object space modifier do not change simply
by moving the object around in the scene.
From: CHAPTER 8– Modeling with Modifiers
3DS MAX AND ITS APPLICATIONS
20. What is the purpose of the point cache
modifier?
• The point cache modifier records
animation information as changes in
vertex location. The vertex information
is saved to a file and can be retrieved
for animation playback.
