Raycast with narrow walkways

I’m really struggling to get a combination of settings that works for these narrow walkways and stairs as well as everything else. Any advice?

The best I can do is make the character width very tiny, but it produces many warnings and still isn’t a perfect result.


I would recommend that you reduce the cell size. The cell size is effectively the resolution of the recast graph and it cannot represent details smaller than that. See RecastGraph - A* Pathfinding Project
