When I tried this I used the manual settings (just created a mesh and set it to nav mesh physics). It didnt do 90 degree vertical polys well but if they were sloped a little it worked fine.
You’ll need your own method for following the generated path.
I have a script that if you have a nav mesh it will follow the points for you… I also has a working turn speed built in… (That was the main reason I made it.) I think it would your for you… You just need to make the nav mesh. I’ll post Tue script tomorrow. (That’s when I finally have internet:) )
