Creates a constraint.
Soft/Rigid Bodies > Create
Constraint > 
Sets the options when
creating a constraint. Here are the options:
- Constraint Name
-
- Constraint Type
-
Choose one of: Nail, Pin, Spring, Hinge, Barrier.
- Interpenetrate
-
If you want the rigid bodies
to penetrate each other rather than collide upon contact, turn on
Interpenetrate.
- Set Initial Position
-
If you want to specify the constraint’s
initial position, turn on Set Initial Position and
enter X, Y, and Z values for the position.
If you don’t turn on Set Initial
Position, a constraint is created either at the midpoint
between the two rigid bodies (extending from one rigid body’s center
of mass to the other’s center of mass), or at the center of mass
of the rigid body, depending on the type of constraint.
Spring Attributes
- Stiffness
-
Sets
the rigidity of the spring constraint. The greater the value, the
greater the force the spring exerts on the body for the same displacement.
- Damping
-
Mutes
the spring action. A high value brings the rigid body to rest faster.
A low value brings the rigid body to rest slower. A negative value
increases the spring’s force on the rigid body. A spring with a zero
or negative damping value never comes to rest.
- Set Spring Rest Length
-
Enables you to set the Rest Length.
- Rest Length
-
Sets
the length the springs try to reach when you play the scene. If
you don’t turn on Set Spring Rest Length, the Rest Length is
set to the same length as the constraint.
