How to get AI to swim?

So I want to get my AI to swim, at the moment they run and walk and patrol the map but I want it so that they can swim, I have this set up for my character but i’m not too sure how to get the AI to swim when they go into the water which is a physical mesh. Any thoughts on where to start?

Hi!You mean diving too or only swimming on surface?

on begin overlap set movement mode to swim. that is if they are of the character class. if you want them to be able to actually move in the 3d space that is the water then you will probably need a nav solution for 3d space.
