hey masas glad you found my Answer suitable for your Problem. I can think of 2 ways approaching the Rope.
The first one is the Cable Component that is good for a Rope or solid continues Mesh.
The second one is to use Multiple Constrains chained together that is useful for not Continously Conected Meshes like Chains for Example.
I tried to google a Example for you and found this Video that basicly shows you exactly what I mean Unreal Engine 4 - cable and physics constraints - YouTube
Note its also Possible to use Splines but I think you would have more trouble to Manage them than its worth. Stick with one of the two methods above I would recommand you.
Have Fun with Physics =)
