Physics constraint strange behavior
I have this strange problem with physics constraints. Attached is a simple project which demonstrates the problem. The scene contains 2 actors: a cable actor with a physics constraint component and a sphere static mesh actor. The sphere is attached to the cable actor via physics constraint so that the sphere "dangles" with a cable attached. My project also has the "degrees of freedom" set to YZPlane. LinearZ is limited to 100 and Swing 1 and 2 are locked. This works as expected, but when I set LinearZ to something larger like 200, the sphere begins to shake violently as in the attached screenshot. Does anyone know what is going on? Thank you.
Try putting the Physics Constraint in the world as a separate actor (superimposed with the cable actor) rather than attached/parented to the cable actor. It seems to fix the issue in your case (even if it's more like a workaround).
