heyas; when you put the base joint parameters on your clothing, especially thick or puffy clothing, chances are your clothing mesh sticks out beyond the joint limits. you can adjust the jp limits (wave the arms of the red and green bend X around, and/or move/size/rotate/turn on-off the sphere zones) without messing up the conformation. as for what the sphere zones do, they help put a cap on the extent of the influence of the bend X (or twist bar) controls. that is, they keep the influence of the jps within the spheres. i have a very, very, basic jp explanation on my web site (last i recall...) check that out, that should explain it better :)
