Creates a constraint.

Soft/Rigid Bodies > Create Constraint >

Sets the options when creating a constraint. Here are the options:

Constraint Name

Name of the constraint.

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.
