I've been trying for almost 2 days now, reading tutorials (there's only some old ones) and experimenting with Terragen. My problem is that I really can't get the skybox seamless.

Maybe something is wrong with camera direction, camera FOV or something. I've done as the tutorials say and I've even experimented on my own for many hours, but I really can't get it to work.
Do someone have any idea what could be wrong?... and might there be an easier/better solution to create your own skybox than using Terragen?
