(working with A6.5) MED seems to have a limit of creating a 500 * 500 vertices hmp. Now is there some way to go round this?
If a huuge (Oblivion) world was created out of MANY 500*500 hmps, that would work if the edges would be seamless. However I have not been able to achieve this... is there some way or some tool to get it right?

(I have tried to make a 1000*1000 pixel grayscaled heightmap in Photoshop, and then cut out 500*500 sized pieces and tried to make those as separate hmps that SHOULD join, but with bad luck).
- Now I face a new problem... when I import a heightmap from a pic, and put 500*500 vertices to it, there is nearly NO height difference, as the HMP becomes VERY FLAT, if i again put a small number of vertices 50*50, then there is a big height difference.
So, how could one achieve great height differencies, even with a high resolution hmp?

How do u make huuge levels, or do u have solutions to the problems I face?
