hello all - I've read the map making guide and searched the forums - but am still a bit perplexed - does water always have to exist on map_h at height 0? or does it merely always have to be at the same level? and are the rules for sea vs rivers or lakes different?

Example - if you have a river flowing into the sea, the river must be at height zero along its whole length, but if a river is on a map with no ocean, then it doesn't matter what the height is on map_h as long as it is level?

Thanks for your help. --viking
