Okay, I suppose it's a good candidate for the silliest question of the year, but how can I avoid my object's faces from "exploding" when I apply a displacement map? I've just started to experiment with displacement maps and so I took a very simple object, a cube, I mapped it (box mode) and then realized a very simple dis-map: it's all filled in mid grey (R=G=B=128) except for a round area filled with a radial gradient going from black to mid-grey. In my mind the rendered result should be a cube with a gradient hole in the corresponding face... That's what I got, but all the faces of the cube literally explode (click image above). I supposed (maybe I'm wrong) that the mid-grey would constitute a sort of baseline, with the displacement taking effect only in the areas with different shades of gray. Surely I'm getting something wrong. I'll appreciate very much anyone who'll care to help. Thanks,        Alberto
