Hi all!
I have two questions about the Hinge joint.
First of all, is there any way to make a PhysicsHingeJoint to make it stronger? I mean not to reaction on any slight force requiring a minimum.
The other one, is there any way to make the Joint apply forces to itself in order to try to mantain a deault position?
Thank you in advance
Look at TestHingeJoint for using its motors, the 6dofJoint also has motors, most joints also have damping values, for more info about bullet joints try looking in the bullet forums too.
Thank you for your comment normen. As I only need a simple hinge joint (6dofJoint would be too much 
) I will try using the motor.
