Is it possible to controll player transmission / Transmit State ?

[AuriRex]

My goal is to create a live Outline (see through walls) on specific Players with halo.Add() and everything has worked thus far, but the  big problem is whenever a Player is outside of the Clients PVS (Potential Visible Set / Whats Rendered by the Engine) then the Outlined player doesnt update and the outline is "stuck" for multiple seconds until it gets updated 2-6 seconds later.

I tried setting UpdateTransmitState() on MetaTable Player to return TRANSMIT_ALWAYS like described with entities here on the wiki and setting self:AddEFlags( EFL_FORCE_CHECK_TRANSMIT ).

I also tried setting self:AddEFlags( EFL_IN_SKYBOX ) but that didn't work either.

I'm unable to find a solution so if anyone knows a way to always update the players on the clients or an alternative please tell me.
