Entity hider for dead NPC's

[SolarWindmill]

Lots of streamers who do inferno use a plugin to hide dead npc's so you dont click on dead nibblers. Its not allowed by jagex but its kinda a "dont ask dont tell" thing among the people that use it. I am wondering how they do this.

I have found older outdated openosrs plugins with the option but I haven't been able to get any to work. any input appreciated.

 

They are using "Entity Hider Extended" from Xkylee repo
