Look at this: http://img841.imageshack.us/img841/1401/texturer.png For whatever reason, when I copy and flip half the map, the textures stop aligning at points like this. Sometimes it isn't a big deal (like in sand, where it is barely noticeable, or concrete) but it is here. The two things I want to fix: textures not aligning and light not casting right on them. There is a weird seam where the light crosses one and hits the other. This might be the same issue? Anyway, selecting everything and aligning it properly doesn't work, and aligning one of it to the left and the other to the right doesn't work, and aligning everything to the center doesn't work. Is there a trick I am missing?
