I know this is an old topic and I was having a similar problem with the hands not showing up in first person view. Since I found out why after looking through and comparing the files with TESVEdit. I see that the creation kit omits the body parts when editing or creating a race. Since I did not find the answer anywhere I decided to put it here to hopefully help out someone who is having a similar problem. I changed my file with TESVEdit and they worked just fine. So I went back into the Creation kit and tried looking for the same information to change and I found it. Here are the steps to get your hands to show back up in the creation kit. Simply open up your race in the creation kit. select the body tab In the "First Person" column click to highlight the following. Body, hands, forearms, ring, shield, and FX01 at the bottom. As you click on them they will get highlighted. Then simply hit ok, save your file and start your game. Now your hands and everything that goes with them should be visible again in first person view. P.S. Just in case you are curious I am on 1.8 skyrim and creation kit, with Dawnguard and Hearthfires installed.
