This MCG is a bit of a hack. It turns Visibility On/Off en masse. There's no in between !!! Please do NOT collapse this modifier with it Off as your geo will disappear into the singularity of a black hole...no joke...you'll get a SINGLE vert !!! Yes I could have backed it up into some channel easily but...couldn't be bothered... Had a harder time doing a picture for this than the MCG !!! Like, how do you show the invisible man ???
