For Godot 3.x

You can simply copy the CRTShader.shader code to use on your project; to set it up, just use it in a an TextureRect with a white texture. Your game must be running 'under' the node for the CRT Shader to have any effect.

You can modify the values of the Shader using the Uniform Variables.

How the Shader works

This Shader is made of 3 main components:

  • Distortion: It is the effect that causes the '3D'-like monitor effect.
  • Color Bleeding: Creates a small 'color bleeding' on the Red and Blue channel of close pixels.
  • Scanlines: Creates a strip of black, alpha lines that moves constantly on the screen.

All the effects have Uniform variables, so they can be controlled without changing the code.

The effects are based on these articles:
