DarkRP Post Process

[Dratyti]

Hello everyone, I recently saw a server for HL2 tiory where you would choose a job, for a certain of them you are given the Post Process, I want to ask how you can turn on the Post Process for a certain profession, that it turned on automatically when you take the profession. I want to add Post Process> Overlay> Binocular to the server. Who can help in advance thanks.

		lastTexture = texture
	end

	if ( mat_Overlay == nil || mat_Overlay:IsError() ) then return end
		render.UpdateScreenEffectTexture()
		mat_Overlay:SetFloat( "$envmap", 0 )
		mat_Overlay:SetFloat( "$envmaptint", 0 )
		mat_Overlay:SetFloat( "$refractamount", refractamount )
		mat_Overlay:SetInt( "$ignorez", 1 )
		render.SetMaterial( mat_Overlay )
		render.DrawScreenQuad()
