UE4 Pathfinding...basic AI

[=alg0801;7178]
Hi, I’m new here. I’m fairly familiar with A* pathfinding system using a GridMap (Unity) and modifying existing systems to make them work how I wish. However, I’ve never worked with Unreals NavMesh system.

BUT I could use a slight nudge on how to get started with UE4’s NavMesh to path AI’s around randomly depending on behavior. Also a noob to Visual Programming (BP) but I shouldn’t need to dive too deep into that immediately to get some simple AI working. I couldn’t really find any tutorials or documentation on how to set up a basic AI Agent that paths. When I tried to view the NavMesh example, the BP_Pawns don’t have any Graphs attached to them (that I can see…)

I want to get a capsule walking around a level to random locations. Upon reaching his destination (or if he’s unable to reach it) he should find a new valid target position… What are are the basic steps for this?
Can you guys point me towards documentation or list out the commonly used classes for Pathfinding?

Thanks in advance!

To come later: Getting Agents to communicate between each other along with distance checking to determine their behavior in the most efficient manner…

Me too interested to a tutorial about navmesh usage.
