well that is how it was designed, unfortunately.  You can try this fun trick... Use two suits. Hide the hands on one and the rest on the other... Works great. There're are a lot of really fun things you can do with two suits.

Quote - I've had some problems with the "All Seams In" preset for the Supersuit.
It looks fine for medium distance shots, but the hands/gloves don't appear right in closer shots.

If I apply the preset the skin shows on the hand and finger finger areas.
I tried hiding the fingers to see what happens, as shown in last picture.
The preset appears to be fully body, so seams can't be adjusted by area.

Of course, it's entirely possible that it's my system thats doing this.  I've had things in the past that work fine for everyone but me.
