hey... phil, where'd you get green and red mag zones from?? ive heard of inner and outer mat spheres for jp's, but even those dont come in red and green on mine. :) the base is the starting point, or reference point for the distortion. (ie: if you rotate the magnet, what are you rotating it around?) the zone is the falloff area, with the center being the most distortion. and the magnet is NOT a magnet, but a representation of what you are doing to the vertices. (ie: moving, scaling, rotating, etc.) check out those tutorials, they'll make everything clear. :)
