NavMesh and scale?

Hi, when my character’s scale is 1.0 or even up to 1.5, the navmesh system works fine, however, when I try to scale up the actor for 2.0 or more, even when there’s cleary lots of space for him to move, the navmesh does not find a path. I’ve tried changing the agent radius and height in the actor himself, in the recastnavmesh actor and in the project settings. I’ve created a supported agent and yet, none of these options worked for me.

How can I check if the path finding algorithm is working? Is there a detailed tutorial online only about navmesh volumes and agent size? All the documentation I can find just quickly gives an overview about how to create a navmesh volume and then jumps straight into AI creation, just assuming navigation is working fine.

Thanks in advance!

Turns out I assumed the navigation had been rebuilt, but was not. However, still looking for a good tutorial if anyone can help, though.
