Pathfiding not working outside Layout?

It was a map Bigger than the Layout

The pathfinding object only work when :

1) The Object is within Layout before finding path.

2) The Destination is within the Layout

will not work even you scroll to other part of the Map.

it only work within the original Layout Position.

Why? Need Help.

Thanks.

This is covered in the manual entry on Pathfinding:

Note all cells outside the layout area are always obstacles. Areas outside the layout area cannot be included in the pathfinding grid, since doing so would require an infinite amount of memory.

Erm.. any suggested solution?

solved myself.

Make layout as big as map.

but viewport size remain.

problem solved. Thanks.
