I need to put a border region in a 5120x5120 worldspace to prevent players from going out the playable area, so in CK I opened region editor, selected my worldspace, created a new region, put a tick in the border checkbox, but where I should draw borders of my region I can't visualize the entire worldspace: http://s1295.beta.photobucket.com/user/PelinalWhitestrake/media/Region_zps3790a985.jpg.html#/user/PelinalWhitestrake/media/Region_zps3790a985.jpg.html?&_suid=136066747859606111770922455086 as you can see (red circle) the most left cell I can visualize is -37,19 (the screenshot didn't take the mouse cursor but it was in the green circle), while being 5120x5120 my worldspace has its most left cell at -80,79.
How do I create a border region if I can't draw it?
