Child Displays the name of the second rigid body attached to the constraint.
You assign the child object by clicking this button and then selecting a rigid
body from any viewport.
Align Spaces To Use these options to align the bodies' local constraint spaces.
You can find out more about each option in Working With Constraint Spaces
on page 3928.
Lock Relative Transform When on, the relative transform between the child
and parent constraint spaces is locked: If you move either space in the viewport,
the other space moves and rotates along with it, and vice-versa.
Strength group
Strength/Tau Govern the impulses applied to the constraint's bodies in order
to maintain the constraint, and so how strongly the constraint works to restrict
their movement. You can find out more about these parameters in
Strength
and Tau
on page 3944.
Breakable group
Breakable When on, the constraint is breakable. If its breakable limits are
exceeded during simulation, it ceases to exert impulses on the attached objects.
You can find out more about breakable constraints in
Breakable Constraints
on page 3944.
Display group
Size Lets you change the size of the constraint space display in the viewport.
Reset Default Values Returns the constraint's parameters to their default
values.
