ok i figuerd out that if you erase the water then hit control+left click and move the terrain what you just erased will show up,no need to save and close-then reopen everytime you erase some water,some of it shows up already painted and some of it dosent.i like this TE dont get me wrong,but making a new custom terrain is going to be more time consumming than the previous editer.maybe if the erase water brush was as big as the paint brush it would make things quicker,as of now its about one third the size.i loaded a greyscale bmp and set the elevation and that worked out good as far as i can tell for now.however when i made a map and try to convert it to 8bit it wont show up in gimp,havent tried photoshop yet but im guessing ill get the same results.
