ok , proofed you are right ,
its realy one byte on a static adress,
the are some other values that check when v is pressed but only this is the value for the animation
Tutorial how to get the basic adress for /v:
1.Download TSearch and use a clean sro not sm or something
2.Go ingame and search with tsearch for unknown values
4.search next "value not changed"
5.open taskmanager , press v ingame , switch to taskmanger by clicking on it , then let the key goes up , then click ingame all people are hiden.
6.repeat 4 and 5 until you have 20memory values left.
7.Add them to the list
8.you can see you have only some values behind each other, 0001,0002,0003,0004
switch from dword to byte and look if something changed when you disable the chars ingame with v
9.delete the useless adresses.(aroud 3 adresses left)
10.use the freez function or change the value by the tsearch list, only one value adress change the models ingame from hide/show
