I come from the Doom modding community, and the Doom map editor I use (DoomBuilder) has a feature in the 3-d view where you can point your cursor to a wall and use the Auto Align function.
What it does is, it scans for all the walls connected to it that have the same texture name and aligns them automatically so there aren't any ugly seams.
Is this possible in Worldcraft 1.6? I've look around for about an hour but can't seem to find such a feature other than having to manually offset the textures brush-by-brush.
