Interesting stuff. That's really a cool thing, because I can enable glow on specific players in CS:GO. Gotta mess with it.
EDIT: I havent tested plugin yet, but got some notes.
Reading through the code, dont use MAXMODELLENGTH, use PLATFORM_MAX_PATH instead.
On a death event, why you initialize client instead of doing RemoveSkin(GetClientOfUserId(GetEventInt(even t, "userid"))) ?
I would switch to player_hurt event and check if (GetClientHealth(client) < 1) if necessary. Because sometimes props wont be removed on player_death event (its late), or it may looks weird in some cases.
Also, does ShouldTransmit hook is really doing something?
Thanks for plugin.
