Sometimes the build process can result in long thin triangles along the the mesh border. This parameters is used during the contour build process to add extra border vertices to prevent this from happening.
Start with a maximum edge length of zero (disabled). If you see a problem, then start with (WalkableRadius * 8) and adjust from there.
