CRT Postprocess - for URP and Legacy Pipelines

Applying this filter will produce a screen effect similar to a retro CRT display.

The screen is distorted like a CRT surface and looks like an old TV adjacent colors blur, and sometimes rainbow blurring also occurs.

Although the setup methods are different for the URP and legacy pipelines, the shaders used are the same and the same effect can be achieved.

Customizable Postprocess Parameters

The following are parameters for NTSCFeature and NTSCPostprocess.

When using URP, use the NTSCFeature parameter; for legacy, use the NTSCPostprocess one.

• Buffer Height
• Height pixel resolution for filter processing. (It will be sharper at higher resolutions, but will lose its retro-display look.)
• Output Height
• Height pixel resolution for screen output. (The number of scan lines is affected by this height.)
• Cross Talk Mode
• Method used for rainbow color bleeding using neighboring pixels.
• [None] No rainbow bleeding is performed.
• [Vertical] Rainbow bleeding is constant on the vertical axis.
• [Slant] Rainbow bleeding is slanted.
• [Slant Noise] Rainbow bleeding is slanted and flickering.
• Cross Talk Strength
• Cross-Talk (rainbow bleeding) intensity. Larger values make the image more vivid, and smaller values make it more black and white.
• Gaussian Blur Width
• The blur width using neighboring pixels. The larger the value, the more blurry the image.
• Curvature
• When turned on, the screen becomes distorted like a CRT.
• Corner Mask
• Circular mask of screen corners; turning OFF eliminates the mask, but off-screen pixels may be visible if Curvature is ON.
• Corner Radius
• Number of pixel radius for circular masks in the corners of the screen. (This value is used only when Curvature is OFF.)
• Scanline Strength
• Strength of the scan line. (0~1: the higher the value, the clearer the scan lines appear)
• Beam Spread
• Scan line beam spread intensity. (0~1) 
• 1: pixels appear to be connected to other scanlines above and below if the pixel luminance is high.
• 0: pixels are not connected to other scanlines above and below.
• Beam Strength
• The larger the value, the brighter the output pixels. 
• Overscan Scale
• Scale value of how much the drawing should be enlarged in relation to the screen. A value less than 1 means the drawing will be enlarged; a value greater than 1 means the drawing will be reduced.
