I am usign the creation kit and am trying to make a new race, I copied wood elf race and clicked prievew full, in the box I just saw it's head with no body, I thought I may hva eclicked the worng one but I definetly haven't, I have tryed it in Skyrim and it has no body! How to I give it a body?

I do know the solution to this, but for the life of me I can't remember. I'll see if I can wrack my brains!

You need to set the Morph Race and Armor Race to match the race you want to 'borrow' from.

Edit: It's in the General Data tab under Copied Data.
