A value of zero indicates non-tiled.
The tile size should usually be between 500 and 1000. A tile size that is too small can result in extra, unnecessary polygons and less than optimal pathfinding. A value that is too large can be result in memory and performance issues during the build process. In general, pick the largest size that also results in a good tile layout along the x and z axes. (You want to avoid creation of thin tiles along the upper bounds of the navigation mesh.)
