Re: btGeneric6DofConstraint - Weld/Parent

There must be some values that can be adjusted? I don't think so. Some old posts say to change the ERP or CFM parameters, but in my tests they don't solve the issue. As drleviathan mentions, multibodies are better, they at least don't pull apart so easily, but they have other issues, like their ang...

btMultiBodyJointLimitConstraint issues

I'm having trouble using a btMultiBodyJointLimitConstraint, as I'm seeing the revolute joint violate the upper and lower limits often. Does anybody know how to make the joint respect the constraint in these two scenarios? Scenario A 1) I start with the InvertedPendulumPDControl example. 2) I comment...
