go to \gorerules\interface\client\Menu and open interface.god

Ctrl+F= search
type umc1
enter
then you should see this:

Code:

@MenuGraph "umc1" {
add_command="show clearprofiles"
add_command="hide clearprofiles"
add_command="playermodel scout"
add_command="show profile1"

add in this command:

Code:

add_command="load sniper.cfg"

do the same for each player (umc2, umc3, mob1, etc..)
make sure you change the cfg for each class (eg: chick.cfg, medium.cfg, etc)

now go in your settings folder and create the cfgs (mech.cfg, medium.cfg, chick.cfg, sniper.cfg, heavy.cfg)

inside each, make any custom weapon binds or anything you want

example:
bind delete:[weapon1]
bind end:[weapon2]
bind pgdn:[weapon8]
crosshair 17

now when you click on the scout, it will load this config file and you will have a new set of weapon binds and a crosshair of choice for the scout.
