How?
Go into your data folder, extract P_HTM_skel01.GR2 or P_HTF_skel01.GR2 depending on gender to override folder.
Now rename them to the appropriate head number, and eureka, you're done!
I've been working on a mod today, and had just finished all the texturing and normal mapping, only to find that after renaming the Tiefling MDBs to 6 and up (To create the new heads) Massive issues occured.
[list][*]The players body made no animations
[*]The Jaw on the facial model freaked out
[*]General ugliness[/list]
Despite this, if I renamed these Editted MDBs to let's say P_HTF_Head01, it functioned perfectly fine, however it then was replacing a head, instead of effectively creating a new one.
Does anyone know what may be causing this issue, and if it can be fixed?
