I wanted to make a quick 3 minute video showing just use a move script with navmesh... But the ramps caused so many problems that I ended up making a general overview of how to understand and fix navmesh baking problems instead.

The video is a bit messy because I didn't fully prepare it for that.
I just went fixing the problems as they appeared instead and added them to the video.

Hopefully you can understand the core problems of navmeshes.

I still want to make a proper navmesh video in the future. Talking about navigation links and jumps.
And a more in-depth one to deal with agents collision avoidance. I've used it before in a few projects, and it worked well, but never properly research it to see if what I was doing was "right".
And eventually one about dynamic navmeshes and moving platform baking.
