I found that in Unreal 5.3, when I connect two Spheres using a Physics Constraint Actor and set all Angular Limits to “Locked,” running “Simulating” in UE 5.3 causes the two Spheres to be completely fixed together. Even if I move Sphere1, Sphere2 follows stably without any shaking.
However, in Unreal 5.4 and Unreal 5.5, under exactly the same parameters, running “Simulating” causes Sphere2 to exhibit significant jitter even when in a stationary state. I found that the main issue lies in the joint where the red and blue lines of the Physics Constraint Actor meet, which visibly shakes. However, I couldn’t find a way to lock it.
Does anyone know how to fix this issue?
