Fields

cameraDepth

Depth at rendering resolution, for the motion vector dilation at silhouettes.

Declaration
public TextureHandle cameraDepth
Field Value
Type Description
TextureHandle

enableTexArray

Indicates whether the textures are 2D texture arrays, as used by XR single-pass rendering.

Declaration
public bool enableTexArray
Field Value
Type Description
bool

historyBlendFactor

Blend weight of the reprojected history. Use 0 when the history content is invalid (e.g. on a history reset): the frame falls back to the spatial upsample but still initializes the history.

Declaration
public float historyBlendFactor
Field Value
Type Description
float

jitter

Sub-pixel camera jitter applied to the pre-upscale frame, in pixels at the rendering resolution.

Declaration
public Vector2 jitter
Field Value
Type Description
Vector2

motionVectors

Motion vectors at rendering resolution, in viewport UV space. Along with the depth and the two history textures, this enables the temporal accumulation; leave invalid for a spatial-only upsample.

Declaration
public TextureHandle motionVectors
Field Value
Type Description
TextureHandle

nextAlphaHistory

Single-channel alpha history the pass writes this frame.

Declaration
public TextureHandle nextAlphaHistory
Field Value
Type Description
TextureHandle

postUpscaleSize

Size of the upscaled output, in pixels.

Declaration
public Vector2Int postUpscaleSize
Field Value
Type Description
Vector2Int

preUpscaleAlpha

Color at rendering resolution, before upscaling. Only the alpha channel is read.

Declaration
public TextureHandle preUpscaleAlpha
Field Value
Type Description
TextureHandle

preUpscalePhysicalSize

Physical (allocation) size of preUpscaleAlpha when it is larger than preUpscaleSize, e.g. with viewport-based dynamic resolution inside a larger texture. Leave zero when the texture is allocated at exactly preUpscaleSize.

Declaration
public Vector2Int preUpscalePhysicalSize
Field Value
Type Description
Vector2Int

preUpscaleSize

Size of the rendered viewport of preUpscaleAlpha, in pixels.

Declaration
public Vector2Int preUpscaleSize
Field Value
Type Description
Vector2Int

prevAlphaHistory

Single-channel alpha history accumulated over the previous frames.

Declaration
public TextureHandle prevAlphaHistory
Field Value
Type Description
TextureHandle

reactiveMask

Reactive mask at rendering resolution, or leave invalid to disable.

Declaration
public TextureHandle reactiveMask
Field Value
Type Description
TextureHandle

stencilExcludeBit

Stencil value that marks the excluded pixels when reactiveMask is a stencil buffer.

Declaration
public int stencilExcludeBit
Field Value
Type Description
int

upscaledColor

Upscaled color whose alpha channel is undefined. Only the RGB channels are read.

Declaration
public TextureHandle upscaledColor
Field Value
Type Description
TextureHandle

viewCount

Number of views to process.

Declaration
public int viewCount
Field Value
Type Description
int
