scenes that have very large textures, a la rge number
of textures, or when rendering a high-resolution
image.
Tip: You can access a
Bitmap Pager Statistics dialog
(page 3–515)
with useful pager information such
as memory usage: Go to Customize menu >
Customize User Interface, find the Bitmap Pager
Statistics item in the Main UI list, and then assign
it as a keyboard shortcut or other UI element.
On—When turned on, the software creates a series
of temporary “page ” files on the drive where it is
installed for use in rendering bitmaps.
Page S ize (kB )—Sets the size of the bitmap page. If
texturesaresmallerthanthepagesize,thesystem
allocates only the memory required.
Bitmap Size Threshold (kB)—Sets the minimum size
(in kilobytes) that a bitm ap must be in order to
be paged.
Memory Pool (k B )—Controls the amount of
memory used by the pager. All pages remain in
memory until this limit is reached. When the limit
is reached, the pager begins saving pages to disk.
Pages that are not frequently used are paged out;
more frequent ly used pages are kept in memory.

Procedure
To prevent transforming unlink ed objects while
worki n g i n IK mo d e :
1.
Choose Customize menu > Preferences >
Preference Settings dialog > Inverse Kinematics
tab.
2. On the Inverse Kinematics panel, turn off the
option labeled Always Transform Children Of
The World.
Single, unlinked objects are hierarchies of one
object.Anunlinkedobjectisitsownrootand
also a child of the world, so turning off Always
Transform Children Of The World prevents you
from transforming single objects in IK mode.
Interfa ce
Applied IK/Interac tive IK group
The threshold and iterations settings are a trade-off
between accuracy and speed. With the two groups
of settings you can individually tune the behavior
of Interactive IK and Ap plied IK. Interactive IK
provides fast, real-time response, so you should set
Interact ive IK preferences for speed. Applied IK
provides the
IK solution (page 3–1049)
to match
the
follow objects (page 3–1037)
very closely. You
should set applied IK preferences for accuracy.
Posit ion—Sets how close the end effector has to
get to the follow object or cursor position for the
