How can I tell if my head is showing up, other than entering the game and having someone tell me?
Delete all the stuff in your override folder (or backup and delete). That will restrict you to the standard Bioware heads.
As I understand it, Layonara uses the CEP heads.
Given this is the case, either extract
all the head models from the Layonara version 3 hakpacks, using
NWN Explorer (the safest option), or download them from the NW Vault (you'll need
this and
this; the not-as-safe option because they haven't been taken from the Layonara hakpacks), and put them into the override folder.
Then you will know that everyone can see your head.
Either that, or you'll have to run around wearing a helm or hood on all the time, which is quite the fashion anyway...
Hope this helps.
