CSB Player Auras gives VIPs a coloured glow-shell around their model. Type say /aura to open a menu, pick from eight colours (or Off), and optionally toggle a pulsing effect that breathes the glow brightness up and down on a task. The aura is re-applied automatically every spawn and cleared on death so it never lingers on a corpse.
set_user_rendering with kRenderFxGlowShell.fun module in modules.ini.csb_auras.sma, copy it to addons/amxmodx/plugins/ and add it to plugins.ini.The menu requires the ADMIN_LEVEL_H flag (t) by default — the flag most shop/VIP systems hand out.
