Add—
Click this, and then select a particle space
warp in the viewports to add the effect to Flex. The
added space warp displays in the list window.
Remove—Select a space warp in the list and click
Remove to remove the effect from Flex.
Deflectors group

be impeded by surfaces. This lets you simulate
collisions with soft-body objects. For best results
w ith collisions, in the deflector settings use a low
value for Bounce and a high value for Friction.
Supported deflectors are:
• POmniFlect (page 2–78)
• SOmniFlect (page 2–84)
• UOmniFlect (page 2–85)
• UDeflector (page 2–89)
• SDeflector (page 2–87)
• Deflector (page 2–90)
List Window—Displays deflectors applied to the
Flex modifier.
Add—Click this, and then select a deflector in the
viewports to add the effect to Flex. The added
deflector displa ys in the list window.
Remove—Select a deflector in the list and click
Remove to remove the effect from Flex.
Advanced Paramete rs rollout
Reference Frame—Sets the first fr ame at which Flex
begins its simulation.
End Frame—When on, sets the last frame at which
Flex is to take effect. After this f rame, the objec t
snaps back to its shape as currently defined by the
stack. For instance, if you animate a Bend modifier
in the stack u nder Flex, then when Flex stops, the
object’s shape is altered only by the B end modifier
settings as of that fr ame.
Affect All Points—Forces Flex to ignore any
sub-object selec tion in the st ack and apply itself
to the entire object.
Set R efer ence—Updates the viewports.
After moving the effect center, click Set Reference
to update the viewports.
Reset—Resets vertex weighting to the defaults.
Advanced Springs rollout
Use these sett ings when you need a more precise
springs setup than is prov ided by the Simple
Soft Body feature. Flex uses two types of spring:
edge springs, which create springs only along
existing edges, and shape springs, w hich can exist
between any two vert ices in the object that are not
connected by an edge. In general, add edge springs
alongexistingedgesandshapespringsbetween
ver tices that don’t share an edge.
Note: Before using these controls, go to the Weights
& Springs sub-object level.
Note: Additional spring types are available using
MAXScript. See the MAXScript reference for
details.
