Hi Luskos, I'm still playing around with terrains myself but I've learnt that if you export your terrain as a .x file with supertexture(s), when you import that .x file it should align the quads for you.
I also found out that you don't have to use the 'Texture Object' command to texture your terrain. All you have to do is load the .x file with the DBPro mode as 3 but you have to have the supertextures as apart of your
project so that they show up under the media tab. This should texture the terrain as you see it in terrain editor.
Load the .x object like this:
Load Object "Your_terrain.x", 1, 3
Using the above method I was able to load the castle example terrain (located in the teds folder) but I am still working on how to properly load the props.
I've attatched an image so you can see what it looks like.
Good luck with your terrains!!!
