CRT effect
Applies a CRT effect, simulating an old cathode-ray tube television.

Apply it to a layer to give your whole game a retro, arcade look. The effect combines several elements you can dial in independently: curvature bends the screen like a real tube, vignetting darkens the corners, and noise adds static. You can also animate the scanlines: set the Interlaced Lines Speed to make them scroll, and the Noise Frequency to control how often the static is refreshed (set it to 0 to freeze the noise).
