You can write your topic however you want, but you need to answer these questions:
So I was creating a roblox infinite map illusion in which the player gets teleported back, the problem is when I teleport the player it always causes it to flicker is there any way I can fix this or make a illusion like this but better?

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local chunking = {}

local Player = Players.LocalPlayer
local Character: Model = Player.Character or Player.CharacterAdded:Wait()
local HumanoidRootPart = Character:WaitForChild("HumanoidRootPart")

-- // Params
local params = RaycastParams.new()
params.CollisionGroup = "RayRoad"
-- // Params

-- // PRIVATE VARIBLES // --
local Limit = 7000
local Back = 5000

local globalConnection = nil

-- // PRIVATE

--// Modules // --

local Effect = require(script.Parent.Parent:WaitForChild("Effects"):WaitForChild("Loader"):WaitForChild("Loader"))

--// PRIVATE FUNCTIONS // --

function chunking:Start()
	globalConnection = RunService.RenderStepped:Connect(function()
		local hrpPos = HumanoidRootPart.Position
		if hrpPos.Z >= Limit then
			Effect:ClearVFXCharacter(Character)
			HumanoidRootPart.Velocity = Vector3.new(0, 0, 0)
			Character:PivotTo(CFrame.new(hrpPos.X, hrpPos.Y, Back) * CFrame.Angles(0, math.rad(180), 0))
		end
	end)
end

function chunking:End()
	globalConnection:Disconnect()
end

return chunking

Try doing .PostSimulation instead.

Why do you need to clear the trail?
