I've had a problem finding out how should config file (csgo/cfg/sourcemod/plugin.NadeTails.cfg) look like. So, if someone interested, here is a working example:
Code:
sm_tails_enabled 1
sm_tails_allowplayers 1
sm_tails_defaultalpha 200
sm_tails_defaulton 0
sm_tails_enablehetails 1
sm_tails_enableflashtails 1
sm_tails_enablesmoketails 1
sm_tails_enabledecoytails 1
sm_tails_enablemolotovtails 1
sm_tails_enableinctails 1
sm_tails_tailtime 20
sm_tails_tailfadetime 3
sm_tails_tailwidth 1
