670 Chapter 12: Animation
New—
Creates a new simulation. Its name consists
of the word "Dynamics" appended by a number,
starting with 00. This number is incremented by
one for each new simulation.
Remove—Deletes the current simulat ion. Dynamic
simulations c an use a lot of memory. Remov ing
old or unused simulations reduces the size of your
.max files. When you remove a simulation, al l
timings and other settings are deleted. However,
any keys generated by the simulation remain.
Co py—C reates a duplicate of the current dynamics
simulation. All of the settings are identical to the
original simulation, with the addition of “01”
appended to the name.
Objects in Simulation group
Lets you add and remove objects from the
simulation, and edit the pro perties of objects in
the simulation.
Edit Object List—Displays the Edit Object List
dialog (page 2–677)
, which lets you specify w hich
sceneobjectsaretobeincludedinthesimulation.
Edit Object—Displays the Edit Object dialog (page
2–673)
.
TheEditObjectdialogisthemaininterfacefor
object dynamics attributes. Use this dialog to set
collisions, effects, surface properties and mass for
each object in the simulation.
Select Objects in Sim—Adds all objects in the
simulation to the current selection set. One use
for this function is to bri ng selected objects into
Track View for further manipulation, keyframe
reduc tion, and s o on.
Effects group
Specifies which effects are included in the
dynamics ca lculation.
Effects by Object—Only effects assigned to specific
objects with t he Edit Object dialog > Assign Object
Effects button are considered in the calculation.
Global E ffects—Only effects included in the Assign
Global Effects dialog (accessed by clicking the
button of the same name) are included in the
calculation.
Assign Global Ef fects—Displays the Assign Global
Effects dialog.
Select effects (space warps) in the list on the left
and use the > button to move them to the list on
the right. Effects thus chosen affect all objects in
the simulation except unyielding ones.
The Assign Global Effects dialog functions
similarly to the
Edit Object List dialog (page
2–677)
.
Collisions group
Specifies which collisions are included in the
dynamics calculation.
Collisions by Object—Collisions assigned to
specific objects through the Edit O bject dialog >
Assign Object Collisions button are included in
the ca lculation.
Global Collisions—Col lisions assigned in the Assign
Global Collisions dialog (accessed by clicking
the button of the same name) are included in the
calculation.
Assign Global Collisions—Displays the Assign
Global Collisions dialog.
Select the objects in the list on the left and use the
>buttontomovethemtothelistontheright.All
objects thus chosen collide with each other in the
simulation.
The Assign Global Collisions dialog functions
similarly to the
Edit Object List dialog (page
