Nav mesh looks weird; won't go up ramp correctly

I have been trying to setup the nav mesh. It hasn’t been going well.

Here are some things to notice in the pics.

-The line (referring to the navmesh) is really thin on the platforms

-The line curves at an angle when going up the long ramp (This is the most concerning)

How do I get this navmesh smoothly traveling across something like this?

hey sorry to rez a dead thread but did you ever fix this issue am having the same problem

Make your platforms bigger. Nav mesh usually leaves a margin from the edges, and if your platforms are narrow like in the screenshots, the nav area will be tiny.
