If you want you can check my thread here, it is very informitive but chaotic and not completly update.
As an example if you have a favorite skin in the game from an NPC and want to use that as your PC skin
it is no longer necessary to copy the files you want to the correct PC directory, you can do it by just
editing your Vampire\vdata\system Clandoc000.txt like this.
Here is my Malk skin I use Heather's Goth outfit, as it is arguably one of the best outfits. :P
"F_Body0" "models/character/npc/unique/santa_monica/heather/heather_goth.mdl"
"F_Body1" "models/character/npc/unique/santa_monica/heather/heather_goth.mdl"
"F_Body2" "models/character/npc/unique/santa_monica/heather/heather_goth.mdl"
"F_Body3" "models/character/npc/unique/santa_monica/heather/heather_goth.mdl"
"F_Body4" "models/character/npc/unique/santa_monica/heather/heather_goth.mdl"
"F_Body5" "models/character/npc/unique/santa_monica/heather/heather_goth.mdl"
By doing it in all 5 slots it causes all armors to be the same outfit or you can make each outfit, each of Heather's
or use a different NPC for each outfit if you wish. :)
You will need to Unpack you files if you really want to see Bloodlines at its best.
That link is very active it has more views than the Official Patch so if you have a question someone will
get to it. :)

It is not really to much trouble and lots of fun, just need a extra 2 gig of space for the unpacked files if you do it now it will overwrite the Unofficial
Patch but you can just recopy Unofficial after unpacking.
Another fun thing you will see in the thread is setting Jump to high making it seem more like your a Vampire at least to me, I set my Jump to 100 or 125.
