Implementing D * lite in UE4 for a project

Hi all

Im a student currently trying to implement dynamic pathfinding for my fyp. Im been working with UE4 for the past few weeks because I decide to try and implement the D * lite pathfinding algorithm in a level.Im wondering is there anyone on here with knowledge on this subject.I dont know where to really look into overwriting ue4 pathfinding with my own attempt. I think it may be in UNavigationComponent but im not certain

Im using unreal 4.6.1

Thanks for your time and any help you may offer.Have a nice day
