UE 4.2 - How to use Navigation Raycast node for AI characters, instead of navigation volumes?

Hi, i have a plugin that doesn´t allow traditional AI Navigation volumes, so, i need to create navigation for my AI in a different fashion, investigating i discovered the Navigation Raycast node, does some one knows how can i use Navigation Raycast node as main Navigation for AI characters? I did not found any video tutorials nor much information to use it instead of navigation volumes.

Please help with BP images,
