VignetteAsset

Remarks

Three effects in one node because they are one shader, and they are one shader because they are always applied together at the very end and each is a few instructions. Three full-screen passes would cost three times the bandwidth to save nothing.

⚠ After the tonemap. All three model the camera and the film rather than the scene. Grain applied to scene-referred light in particular is invisible in shadow and enormous in highlights, because it is a fixed amount added to an unbounded number.

Fields and properties (22)

• public string Name

  The node's name, for debug groups and for a human reading the file.

• public bool Enabled

  Whether the node runs.

• public string Source

  The image it degrades.

• public string Output

  The name the result is published under.

• public PixelFormat Format

  The format of the target it declares.

• public bool UseVignette

  Whether the corners are darkened.

• public bool UseChromaticAberration

  Whether the channels are offset radially.

• public bool UseGrain

  Whether grain is added.

• public bool LuminanceWeightedGrain

  Whether grain scales with darkness, as real film does.

• public float VignetteIntensity

  0 is no darkening, 1 is fully dark at the corners.

• public float VignetteSmoothness

  How abrupt the falloff is. Higher keeps the centre clear for longer.

• public float AberrationStrength

  Channel offset at the screen edge, in UV units.

• public float GrainIntensity

  How much grain there is.

• public float GrainScale

  How large one grain is.

• public Vector3 VignetteColour

  What colour the corners go towards.

• public Vector2 VignetteCentre

  Where the vignette is centred, in UV. The screen's middle is (0.5, 0.5).

• public float VignetteRoundness

  0 follows the aspect ratio, 1 is a circle whatever shape the screen is.

• public bool UseLensDistortion

  Whether the image is warped radially before anything else reads it.

• public float DistortionIntensity

  How far the image is pushed out (positive) or pulled in (negative) at the edges.

• public Vector2 DistortionScale

  Per-axis multipliers, so one axis can be left undistorted.

• public Vector2 DistortionCentre

  Where the distortion is centred, in UV.

• public float DistortionZoom

  A zoom after the warp, to hide the border a positive distortion pulls in from.
