public sealed class TextModeCRTSettings
Remarks

A TextModeCRTPreset stores one of these, and a TextModeCRTDriver holds its own copy, which starts as a copy of its preset and can then be edited freely. Copy values between instances with CopyFrom(TextModeCRTSettings), which does not allocate.

Colors are authored like any other Inspector color and converted to linear light where the shader needs it. Time constants are in milliseconds.

Fields

BeamBlend

How much the beams of neighboring scanlines overlap. 0 draws every pixel from its own scanline only; 1 sums the neighboring beams, as on a real tube.

Declaration
[Tooltip("How much neighboring scanlines spill into each other. 0 draws every pixel from its own scanline, which keeps thin dark text on a bright background crisp. 1 lets bright lines bleed into their neighbors as on a real tube, which looks softer and washes out dark text on bright backgrounds.")]
[Range(0, 1)]
public float BeamBlend
Field Value
Type Description
float

BeamWidthMax

Width of the electron beam on the brightest content, in scanlines (Gaussian sigma).

Declaration
[Tooltip("Width of the electron beam on bright content, in scanlines. A real beam widens with brightness, so bright lines come closer together than dark ones. Keep it near 0.3 for visible scanlines; above 0.4 bright text shows none.")]
[Range(0.1, 1)]
public float BeamWidthMax
Field Value
Type Description
float
Remarks

A real beam widens as it gets brighter, so bright lines sit closer together than dark ones. The range is MIN_BEAM_WIDTH to MAX_BEAM_WIDTH. This value may stay below BeamWidthMin; the composite then draws the bright beam at least as wide as the dark one (see Sanitize()).

BeamWidthMin

Width of the electron beam on the darkest content, in scanlines. The value is the sigma of the Gaussian that models the beam's vertical profile.

Declaration
[Header("Beam")]
[Tooltip("Width of the electron beam on dark content, in scanlines. Values around 0.2 leave clear dark gaps between scanlines; values above 0.4 close them.")]
[Range(0.1, 1)]
public float BeamWidthMin
Field Value
Type Description
float
Remarks

Smaller values leave clearer dark gaps between scanlines. The range is MIN_BEAM_WIDTH to MAX_BEAM_WIDTH. BeamWidthMax sets the width for the brightest content, and the beam widens between the two as brightness rises.

BezelColor

Color of the bezel around the picture, and of any area that the rounded corners, the curvature or an Overscan below 1 leave outside the tube.

Declaration
[Tooltip("Color of the bezel around the picture, and of the area rounded corners or curvature leave outside the tube.")]
public Color BezelColor
Field Value
Type Description
Color
Remarks

BezelWidth controls whether a bezel frame is drawn around the picture at all.

BezelReflection

How strongly the inner edge of the bezel reflects the picture.

Declaration
[Tooltip("How strongly the inner edge of the bezel reflects a blurred copy of the picture.")]
[Range(0, 1)]

Field Value
Type Description
float

BurnIn

[Range(1, 3)]
public float CRTGamma
Field Value
Type Description
float
Remarks

The shader applies the ratio CRTGamma divided by DisplayGamma to the picture. When both values are equal the ratio is 1 and the step is skipped, so the colors stay untouched.

ChromaBandwidth

Bandwidth of the color signal in MHz. Lower values smear color further along each line.

Declaration
[Tooltip("Bandwidth of the color signal in MHz. Most home televisions decoded about 0.6 MHz, which smears color visibly; broadcast NTSC carried up to 1.3 MHz, a VHS tape about 0.5. Lower values smear colors further to the right and left of where they belong.")]
[Range(0.1, 4)]
public float ChromaBandwidth
Field Value
Type Description
float

White point of the tube in kelvin. The default NEUTRAL_COLOR_TEMPERATURE (6500 K) leaves white neutral; higher values shift it toward blue and lower values toward orange.

Declaration
[Tooltip("White point of the tube in kelvin. Many sets, especially Japanese ones, ran at 9300 K, which is noticeably blue.")]
[Range(3000, 12000)]
public float ColorTemperature
Field Value
Type Description
float
Remarks

The range is MIN_COLOR_TEMPERATURE to MAX_COLOR_TEMPERATURE.

Turn it off for the heavier look of a cheap set. Needs NTSC with a line shift of 0.5; PAL uses its delay line instead.")]
public bool CombFilter
Field Value
Type Description
bool

Field Value
Type Description
float

Convergence

Convergence error at the edges of the picture, in screen pixels: the red beam lands outward and the blue beam inward, growing from nothing in the center.

Declaration
[Tooltip("Response curve the content was made for. Leave at 2.2 for text and pixel art; set both gamma values to 1 to leave colors untouched.")]
[Range(1, 3)]
public float DisplayGamma
Field Value
Type Description
float
Remarks

See CRTGamma for how the two values combine.

ExactScanlinePitch

Whether ScanlinePitch is used exactly as set. Off, the pitch is lowered for small text so every character row keeps enough scanlines to stay readable; on, it is kept even when that makes small text harder to read. Meant for a pitch someone chose on purpose, such as one set at runtime, rather than a preset's general default.

Declaration
[Tooltip("Uses the scanline pitch exactly as set, without lowering it for small text. Turn on for a pitch chosen on purpose; small text may get too few scanlines to read well.")]
public bool ExactScanlinePitch

Methods

ApplyReadabilityClamp()

Limits the values that cost legibility: softness, curvature, glow, persistence, mask strength, noise, jitter, the hum bar, convergence and burn-in, and stops the vertical roll and HDR mask mode, whose full-strength mask costs legibility even at full brightness. Used for screens the player has to read quickly.

Declaration
public void ApplyReadabilityClamp()

Clone()

Creates an independent copy.

Declaration
public TextModeCRTSettings Clone()
Returns
Type Description
TextModeCRTSettings

A new instance holding the same values.

CopyFrom(TextModeCRTSettings)

Copies every value from another instance without allocating.

Declaration
public void CopyFrom(TextModeCRTSettings other)
Parameters
Type Name Description
TextModeCRTSettings other

The settings to copy. Ignored when null.

Sanitize()

Clamps every value into its valid range, so values set from code or loaded from an older asset cannot break the shader.

Declaration
public void Sanitize()

UsesCombFilter()

Returns whether the composite decoder uses its comb filter: CombFilter is on, the signal is composite or RF, the standard is NTSC and the subcarrier is inverted from one scanline to the next.

Declaration
public bool UsesCombFilter()
Returns
Type Description
bool

True if the decoder separates color with the comb filter.
Remarks

The comb subtracts the previous scanline, which cancels brightness and keeps color only when the subcarrier is inverted between the two lines. With any other line shift it would cancel the color instead, so it is left out.

UsesGlow(CRTQualityTier)

Returns whether the glow pyramid runs at a quality tier: the tier is Medium or High, and something reads the pyramid there. That is glow, halation at High (Medium has none), or a bezel with a reflection, which mirrors the smallest glow level at Medium and High.

Declaration
public bool UsesGlow(CRTQualityTier tier)
Parameters
Type Name Description
CRTQualityTier tier

The quality tier.
Returns
Type Description
bool

True if the glow passes run.

UsesSignal(CRTQualityTier)

Returns whether the video signal is simulated at a quality tier: the signal type is not RGB and the tier is Medium or High.
