Unexpected results with RecastNavmeshModifier and colliders

General Recast graph

I am using RecastNavmeshModifier on some objects to make them unwalkable surfaces. However, as you can see from this first screenshot, the graph rises upwards as if it is trying to graph the top of a collider.

The components are definitely doing something because if I disable RecastNavmeshModifiier’s then the graph scans like this:

And to confirm its the selected colliders that are causing the issue, if I set RecastNavmeshModifier to AlwaysExclude then the graph becomes flat (but paths through the objects obviously).

Is this a bug?

If you’re able to I’d try and lower your tile size and go from there. If you’re still having issues with it I’ll try and recreate the scene and see what I can find out.
