Well im new, played the game a bit, decided to make some maps. So here I am working on trial test map. Its nothing special atm but time will tell. But I have run in to a intresting problem, im sure I can figure it out myself, but im lazy and thought i'd see if anyone had a quick answer.
Anywho, heres the attached base texture and height map from my test map, I've followed the tut's and made a texture, its a simple 2048x2048 and the heightmap is 257x257 following the guides this is correct?


(The heighmap currently sucks arse and is only about 20% of what it should be)
Anyhow I thought all was well and went on to do a quick test and fully compiled the map. All went well until I fired up spring and got the following problem... an intresting one no?.

PS the texture imagage is badly compressed so looks awful!
