Following the "Design, Develop and Deploy for VR" course on unity learn and I've got to unit 5 where the DirectionalJointDrive prefab is introduced to control a drawer. Later in unit 6 they use it for a button on a keypad but after following this instruction, I've noticed something is not right.
Even though, as I understand, the DirectionalJointDrive is supposed to be constrained at the joint level, not the rigidbody level, as I use my rigidbody hand avatars to interact, there is absolutely no constraints! It wobbles and shakes on all axis. I've checked their sample project, and theirs doesn't have this problem.
Please can somebody explain why this would be happening??
