okay, I've searched the forum and found nothing to solve this problem... i made a simple polycube and looked at the UV Map Editor. then i started beveling the edges(2 lines), the maps in the editor splitted and i can't sew them. when i select all the edges in the editor, found out that the edges in the beveled parts aren't selected. with this problem, i don't think i can UV map, any hints on my problem?
