PlayerInitialSpawn to change map textures

[Krijag]

Hello! Im trying to make a lua script to change the map textures. The good thing that it works, but it only works after saving it while on the server. It doesnt run on PlayerInitialSpawn. I have asked around for help by a few coder friends i know, but they havent been to much help. Right now this is what i have:
AddCSLuaFile()

hook.Add("PlayerInitialSpawn","PlyJoin",function(met)

local mat = Material"ocrp/rfstamp1"
local met = Material"oslorp/oslo"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/taco1"
local met = Material"oslorp/max1"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/boa1"
local met = Material"oslorp/dnb1"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/boa2"
local met = Material"oslorp/dnb2"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/bh1"
local met = Material"oslorp/naf"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/cobsgm1"
local met = Material"oslorp/bilforhandler1"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/cobsgm2"
local met = Material"oslorp/bilforhandler2"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/gm01"
local met = Material"oslorp/bilforhandler3"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/foods1"
local met = Material"oslorp/rema1000"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/frosty1"
local met = Material"oslorp/cubus"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/grace1"
local met = Material"oslorp/uio"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/quarantine1"
local met = Material"oslorp/eiendomsmegler1"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/rfems1"
local met = Material"oslorp/ambu"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/rffd1"
local met = Material"oslorp/brannvesenet"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/rfpd1"
local met = Material"oslorp/politiet1"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/rfpd2"
local met = Material"oslorp/politilogo"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

local mat = Material"ocrp/transit1"
local met = Material"oslorp/oslotaxi"
mat:SetTexture("$basetexture", met:GetTexture"$basetexture")

end)
Note that the lua file is in lua/autorun/client

GM/PlayerInitialSpawn is a serverside hook.

Try using GM/InitPostEntity instead

Also, there's a category for Garry's Mod specific coding.
My bad! Didn't see it! Ill try InitPostEntity and check if that works
