heyas; you can see very easily what's going on if you go into flat shaded lined, or smooth shaded lined mode in poser. then you'll see the mesh you are working on. now any deformer (magnet, wave, or poser joint bending) can only bend/deform polygons by moving the points -- ie, the corners. if you look at the square in a lined mode, you can see it is really just one square polygon -- it has four points, one at each corner. if you look at the ground at the same time, you can see the ground is not just one square, but a grid of squares. so if you take a magnet (for simplicity of example, here), and put it on the square and on the ground, and you bend it 90 degrees.... on the ground, you will get a smooth bend, but on the square, the two end points will move, but the lines between them just can't bend. there's no points for them to bend AT, between one end and the other.
