Ok, breathing some sense in this topic -
and how can i do any 3d file into a pk3 file??? 
a .pk3 file is an already setup file to be used in-game. Just put it in your "base" folder which is located in your tremulous folder. To open a .pk3 file use programs as WinRar.
i wanted a werewolf without a gun o_O
AND SOME 3D WEAPONS (WEAPONS WICH ARE IN REAL USED)
What are these weapons? Also, you said you don't want them to have guns.

Also, making something in 3D isn't as easy as you might think, and yes, we need concept arts first (however, those previously posted are a bit silly). A werewolf can also be quite different - in some movies or games they are shown differently. Oh, and by the way, I just got a new qoute for my sig, thanks!
