A complete template that allows your player to vault (jump over) , climb, and drop down from obstacles like walls, or fences.
This will be very easy to plug and play on any character, all you need to do is copy and paste the blueprints.
The entire template is also network replicated, works both on server and client players! :)](UE4 - Vaulting and Climbing System Overview - YouTube)
