The textures are all fine and taken properly from a beamng map. Tweaking the texture sizes of the terrain or the material's itself sometimes makes one of them work normally but i wasn't able to get it right yet. Also is there a way to make the heightmap of my terrain bigger than 2048x2048? so i wont have these big square but rather smaller and i could detail more - for reference im making a big 14km wide map.
Maximum you can do is 8k heightmaps. But that's still pretty decent as long as you don't have any areas of really crazy ups and downs.
Yeah my heightmap is 8k now, way better than the 2k i had lol i also was able to fix the black holes so its all good. Takes time to learn all this
