Hi, I actually solved my problem and I think it’s a bug and not a normal oversight. What I did was that I created a 3rd person template then on Windows File Explorer, I copied my original files and pasted it on the new 3rd person template folder I created and overwrite all the files. It worked perfectly after that.

Hi, I’m really stuck here.

I’ve already done the following tutorial and made it work for me before

[![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/3/9/3/393181a848bb2afa3fec5b4b43d7f09ba2d0548b.jpeg "Unreal NPC Characters - UE4 Open World Tutorials #44") ](https://www.youtube.com/watch?v=oo3SSNlOJ5g)

But now I’ve realized, after working on other aspects of my game, it doesn’t work anymore. I’ve tried other things to make my AI move but nothing. I tried the tutorial again on a fresh 3rd person template and it worked. I’m wondering If I’m missing something?

Hope someone could help me.

Pictures below are screenshot of my project. One showing I didn’t forget my navmesh volume, next is the exact node on the tutorial, and last is showing that I got my class AI Controller Class Correct.
