Hi All,

I’m working on a level right now that has a cave that is sloped and connects two rooms. For some reason I cannot get the navigation mesh to show up on the sloped mesh. I have messed with the nav mesh settings and still can’t seem to get it to work.

Here you can see the level and the sloped part of the cave has no nav mesh on it.

Here are my nav mesh settings

I set the Agent Max Slope as high as it would go with no change. Any help is greatly appreciated, I’ve been banging my head against a wall with this.

Thanks!
