Hi, I am trying to simply make a room prop made from three cubes (floor, wall1, wall2). I am fairly literate with poser and computers (I'm a programmer) but for the life of me I can't figure out how to simply group all three cubes together with textures to create just one prop! I've read the book and it's useless. I find the menu isn't very intuitive at all. Does anybody know any decent tutorials, links or maybe a quickie tutorial? I'd appreciate it.
