How to make a ViewportFrame of your ROBLOX Character?

https://devforum.roblox.com/t/rendering-the-character-with-a-viewportframe/241369/31

Post 31 by Boatbomber please read the problem and check out the script of Boatbomber that you can download (don't forget the credits) https://devforum.roblox.com/uploads/short-url/4g9S29Zwdhdfdpsz4v5pOd7i9vQ.rbxm

Edit: Uploaded new file. This version is faster, uses less CPU, and has fewer edge cases. Works properly with tools. CharacterViewport.rbxm (4.0 KB)

CharacterViewport.rbxm (4.0 KB) This is the link to download from the model. I forgot that I could download it myself and send it to you. Here, put this local script in the startergui:

local player = game.Players.LocalPlayer
local ScreenGui = Instance.new("ScreenGui",player.PlayerGui)
local ViewportFrame = Instance.new("ViewportFrame",ScreenGui)
ViewportFrame.Position = UDim2.new(0, 200,0, 0)
ViewportFrame.Size = UDim2.new(0, 200,0, 200)
ViewportFrame.BackgroundTransparency = 1
