Uh, yeah .. forgot to mention that
Implementing a basic authorization right now. Username is "admin", password is the same as for control panel.
Ooookay, was just going to ask how the heck you got a map that big
Actually the coordinates in in game dimensions are minPos and maxPos, so it's -11472/-10352 to 100112/100160 ^^
Hadn't thought about that possibility. Just uploaded a new version that disables rendering of an overview image file if the map is larger than 10k*10k. That should allow you to use "rendermap".
