Bullet > Create Rigid Body Constraint

 
 
 

Sets the select objects as elements used in a Rigid Body Constraint.

Bullet > Create Rigid Body Constraint >

Opens the Create Rigid Body Constraint window.

Constraint Type

Lets you select from the following constraint types:

  • Point
  • Hinge
  • Slider
  • Cone-Twist
  • Six Degrees-of-Freedom
  • Spring Hinge
  • Spring Six Degrees-of-Freedom

For descriptions of each of these constraint types, see: Bullet Constraint Types.

Hide Rigid Body Shape
Makes the Rigid Body shape invisible.
Use Reference Frame
Lets you set a frame of Reference for the constraint axis and limits.
Linear Damping
Lets you set a value between 0.0 and 1.0 with a default of 0.0 for dampening the translation forces. A value of 1.0 fully dampens the forces applied to the translation. Applies to the Slider, 6 Degrees of Freedom constraints.
Linear Softness
Lets you set a value between 0.0 and 1.0 with a default of 0.0 to soften the translation forces
Linear Restitution
Lets you set a value between 0.0 and 1.0 with a default of 0.0 for the restitution (or bounce) of the affected object.
Angular Damping
Lets you set a value between 0.0 and 1.0 with a default of 0.0 to dampen forces applied to the rotation. A value of 1.0 fully dampens the forces applied to the rotation.
Angular Softness
Lets you set a value between 0.0 and 1.0 with a default of 0.0 to soften forces applied to the rotation.
Angular Restitution
Let you set a value between 0.0 and 1.0 with a default of 0.0 for the restitution (or bounce) of the object's rotation.
Linear Constraint X
Lets you define whether a linear translation can be locked, free, or limited on the X-axis.
Linear Constraint Y
Lets you define whether a linear translation can be locked, free, or limited on the Y-axis.
Linear Constraint Z
Lets you define whether a linear translation can be locked, free, or limited on the Z-axis.
Linear Constraint Min
Lets you define the minimum X, Y, and Z translations.
Linear Constraint Max
Lets you define the maximum X, Y, and Z translations.
Angular Constraint X
Lets you define whether the axis rotation can be locked, free, or limited on the x-axis.
Angular Constraint Y
Lets you define whether the axis rotation can be locked, free, or limited on the y-axis
Angular Constraint Z
Lets you define whether the axis rotation can be locked, free, or limited on the z-axis.
Angular Constraint Min
Lets you define the minimum angle, for the X, Y, and Z angles, in degrees (-360 and 360).
Angular Constraint Max
Lets you define the maximum angle, for the X, Y, and Z angles, in degrees (-360 and 360).
Linear Limit Softness
Lets you set a value between 0.0 and 1.0 with a default of 1.0.
Linear Limit Bias
Lets you set a value between 0.0 and 1.0 with a default of 0.3.
Linear Limit Relaxation
Lets you set a value between 0.0 and 1.0 with a default of 1.0.
Angular Limit Softness
Lets you specify the percentage of limit where the movement is free. Beyond this softness percentage, the limit is gradually enforced until the "hard" (1.0) limit is reached. The value is between 0.0 and 1.0 with a default of 1.0. The recommended value is 0.8.
Angular Limit Bias
Lets you specify the strength with which the constraint resists angular limit violation. The value is between 0.0 and 1.0 with a default of 0.3.
Angular Limit Relaxation
Lets you specify how much a constraint resists velocities which violate the angular limits. The lower the value, the less the constraint resists the violation. The value is between 0.0 and 1.0 with a default of 1.0. The recommended value is near 1.0.
Linear Motor Enabled
Lets you enable the powered motor to push linearly. Applies to Slider and Spring 6 Degrees of Freedom constraints.
Linear Motor Target Speed
Lets you set the powered motor target speed. Applies to Slider and Spring 6 Degrees of Freedom constraints.
Linear Motor Max Force
Lets you set the powered motor max force. Applies to Slider and Spring 6 Degrees of Freedom constraints.
Angular Motor Enabled
Lets you turn the motor on the X, Y, and Z axis on and off.
Angular Motor Target Speed
Lets you specify the target velocity for the motor's X, Y, and Z axis.
Angular Motor Max Force
Lets you specify the maximum motor impulse, for each X, Y, and Z axis, that can be applied at a single simulation step. It has a value greater than or equal to 0.0.
Linear Spring X Enabled
Lets you enable the linear spring in X translation. The Spring Hinge and Spring Six Degrees of Freedom constraints support linear and angular springs.
Linear Spring Y Enabled
Lets you enable the linear spring in Y translation. The Spring Hinge and Spring Six Degrees of Freedom constraints support linear and angular springs.
Linear Spring Z Enabled
Lets you enable the linear spring in Z translation. The Spring Hinge and Spring Six Degrees of Freedom constraints support linear and angular springs.
Linear Spring Stiffness
Lets you set the linear spring stiffness for the body. This is a positive value greater than or equal to 0.0. Applies to Spring Hinge (Y-axis only), and Spring 6 Degrees of Freedom constraints.
Linear Spring Damping
Lets you set angular spring dampening for the body. This is a positive value between the values of 0.0 and 1.0; a value of 1.0 means no dampening. Applies to Spring Hinge (Y-axis only), and Spring 6 Degrees of Freedom constraints.
Angular Spring X Enabled
Lets you enable angular spring in X rotation. Applies to Spring Hinge and Spring Six Degrees of Freedom constraints.
Angular Spring Y Enabled
Lets you enable angular spring in Y rotation. Applies to Spring Hinge and Spring Six Degrees of Freedom constraints.
Angular Spring Z Enabled
Lets you enable angular spring in Z rotation. Applies to Spring Hinge and Spring Six Degrees of Freedom constraints.

Angular Spring Damping
Lets you set an angular spring dampening for the body. This is a positive value between the values of 0.0 and 1.0; a value of 1.0 means no dampening. Applies to Spring Hinge and Spring Six Degrees of Freedom constraints (Y-axis only).
