Hello everyone!
I was looking through the sample scenes with UE4, specifically the Cave scene. There are a few rope bridges animated as if moving in the wind. I couldn’t find any specific blenshape animation or skeletal mesh attached in the scene. How did Epic set this up? (sorry if this is a newbie question)
Thanks for your help 
As far as I know they did it in the material
as in animating a displacement map or something like that? i guess that makes sense. It’s the only place i haven’t checked yet. thanks!
[EDIT] ok yes it was done through vertex animation in the materials. Thanks again, this saves me so much time. I have so many ropes to animate and thought i would have to make skeletal meshes for everything. (this would have been a disaster). 
You can move vertices of mesh with World Position Offset and basically “code behavior” for them with different nodes like Sine, Time and etc. I think they also used vertex painting to paint out starting and ending point of rope and then had smooth gradient in between to have nice moving curve later.
