How to Get Motion Blur in Roblox?

Motion blur is an amazing visual effect that can enhance the cinematic feel of your Roblox games. Unfortunately, it’s not a built-in feature, but don’t worry, we’ll show you how to achieve this stunning effect with just a few simple steps. Here’s a step-by-step guide to help you get motion blur in Roblox:

Requirements

Before we dive into the tutorial, make sure you have the following:

  • Roblox Studio

  • A Roblox game project

  • Basic understanding of programming concepts (Lua)

Steps to Get Motion Blur

Follow these steps to add motion blur to your Roblox game:

  1. Create a New Script: Create a new LocalScript in your game’s folder by going to Insert > Script > Local Script.

  2. Import Libraries: At the top of your script, import the math and GamepadController libraries using the following code:

local math = _G.math

local game = _G.game

local Players = _G.Players

local gamepadController = require(game:GetService("UserInputService").GamepadInput:Controller())

  1. Setup Variables: Define two global variables to store the camera and blur value:

local cam

local blur = 5 -- adjust this value to control the amount of blur

  1. Calculate Motion Blur: Create a function that will be called every frame to calculate the blur:

local function update()

    -- Calculate the camera position

    cam = workspace.CurrentCamera



    -- Calculate the blur amount based on camera velocity

    local vel = cam.Velocity / 10 -- adjust this value to control the sensitivity

    local blurVal = (vel.Length ^ (1/2)) * blur

  1. Blur Render Frame: Create a function to blur the render frame using the GraphicsBlurEffect from the Render module:

local function blurFrame(frame)

    local effect = game.Workspace:WaitForChild("Effects"):WaitForChild("GraphicsBlurEffect")

    effect.FinalTransparency = blurVal / (vel.Length ^ (1/2)) * blur

    frame.Materials:Apply(effect)

end

  1. Run the Update Loop: Use a while loop to constantly update and blur the render frame:

local player = game.Players.LocalPlayer

while true do

    wait(1 / 60) -- update every 1/60th of a second (approximately 60 FPS)

    update()

    game.CoreGuiBlurFrame:Get().Frame = blurFrame

    local frame = game.CoreGuiBlurFrame:Get().Frame

end

Tips and Adjustments

Here are some tips to fine-tune your motion blur:

  • Adjust Blur Amount: Experiment with different blur values to achieve the desired effect. Lower values will result in a softer blur, while higher values will produce a more dramatic blur.

  • Camera Velocity Sensitivity: Adjust the vel.Length formula to control the sensitivity of the blur effect.

  • Frame Rate: Increase or decrease the wait time to control the frame rate.

FAQs

Frequently Asked Questions

  1. Can I use this script in any Roblox game?

Yes, this script is general and can be used in any Roblox game project.

  1. Do I need to create a new folder for this script?

No, you can place the script directly in your game’s folder.

  1. Can I customize the appearance of the motion blur?

Yes, you can modify the appearance of the motion blur by experimenting with different blur values and color values.

  1. How do I enable/disabled the motion blur effect?

To enable or disable the motion blur effect, simply uncomment or comment out the entire script in your Roblox game project.

  1. Can I use motion blur with other visual effects?

Yes, motion blur can be combined with other visual effects to create a more cinematic experience.
