Struct RenderGraphUtils.BlitMaterialParameters

This struct specifies all the arugments to the blit-with-material function. As there are many parameters with some of them only rarely used moving them to a struct makes it easier to use the function.

Use one of the constructor overloads for common use cases.

Syntax

public struct RenderGraphUtils.BlitMaterialParameters

Constructors

BlitMaterialParameters(TextureHandle, TextureHandle, Material, int)

Simple constructor to set a few amount of parameters to blit.

Declaration

public BlitMaterialParameters(TextureHandle source, TextureHandle destination, Material material, int shaderPass)

Parameters

Type	Name	Description
TextureHandle	source	The texture the data is copied from.
TextureHandle	destination	The texture the data is copied to.
Material	material	Material used for blitting.
int	shaderPass	The shader pass index to use for the material.

BlitMaterialParameters(TextureHandle, TextureHandle, Material, int, MaterialPropertyBlock, int, int, int, int, int, int, FullScreenGeometryType, int, int, int)

Constructor to set the source and destination mip and slices as well as material property and IDs to interact with it.

Declaration

public BlitMaterialParameters(TextureHandle source, TextureHandle destination, Material material, int shaderPass, MaterialPropertyBlock mpb, int destinationSlice, int destinationMip, int numSlices = 1, int numMips = 1, int sourceSlice = -1, int sourceMip = -1, RenderGraphUtils.FullScreenGeometryType geometry = FullScreenGeometryType.Mesh, int sourceTexturePropertyID = -1, int sourceSlicePropertyID = -1, int sourceMipPropertyID = -1)

Parameters

Type	Name	Description
TextureHandle	source	The texture the data is copied from.
TextureHandle	destination	The texture the data is copied to.
Material	material	Material used for blitting.
int	shaderPass	The shader pass index to use for the material.
MaterialPropertyBlock	mpb	Material property block to use to render the blit. This property should contain all data the shader needs.
int	destinationSlice	The first slice to copy to if the texture is an 3D or array texture. Must be zero for regular textures.
int	destinationMip	The first mipmap level to copy to. Must be zero for non-mipmapped textures. Must be a valid index for mipmapped textures.
int	numSlices	The number of slices to copy. -1 to copy all slices until the end of the texture. Arguments that copy invalid slices to be copied will lead to an error.
int	numMips	The number of mipmaps to copy. -1 to copy all mipmaps. Arguments that copy invalid mips to be copied will lead to an error.
int	sourceSlice	The first slice to copy from if the texture is an 3D or array texture. Must be zero for regular textures. Default is set to -1 to ignore source slices and set it to 0 without looping for each destination slice
int	sourceMip	The first mipmap level to copy from. Must be zero for non-mipmapped textures. Must be a valid index for mipmapped textures. Defaults to -1 to ignore source mips and set it to 0 without looping for each destination mip.
RenderGraphUtils.FullScreenGeometryType	geometry	Geometry used for blitting the source texture.
int	sourceTexturePropertyID	The texture property to set with the source texture. If -1 the default "_MainTex" texture property will be used. Note: Use Shader.PropertyToID to convert a string property name to an ID. If propertyBlock is null the texture will be applied directly to the material.
int	sourceSlicePropertyID	The scalar property to set with the source slice index. If -1 the default "_SourceSlice" property will be used. Note: Use Shader.PropertyToID to convert a string property name to an ID. If more than one slice is rendered using the blit function (numSlices>1) several full screen quads will be rendered for each slice with different sourceSlicePropertyID values set.
int	sourceMipPropertyID	The scalar property to set with the source mip index. If -1 the default "_SourceMip" property will be used. Note: Use Shader.PropertyToID to convert a string property name to an ID. If more than one mip is rendered using the blit function (numMips>1) several full screen quads will be rendered for each slice with different sourceMipPropertyID values set.

Fields

destination

The texture to blit into. This subresources (mips,slices) of this texture texture will be set-up as a render attachment based on the destination argumments.

Declaration

public TextureHandle destination

Field Value

Type	Description
TextureHandle

destinationMip

The first destination mipmap to blit into.

Declaration

public int destinationMip

Field Value

Type	Description
int

destinationSlice

The first slice of the destination texture to blit into.

Declaration

public int destinationSlice

Field Value

Type	Description
int

geometry

The type of full-screen geometry to use when rendering the blit material. See FullScreenGeometryType for details.

Declaration

public RenderGraphUtils.FullScreenGeometryType geometry

Field Value

Type	Description
RenderGraphUtils.FullScreenGeometryType

material

The material to use, cannot be null. The blit functions will not modify this material in any way.

Declaration

public Material material

Field Value

Type	Description
Material

numMips

The number of mipmaps to blit. -1 to blit all mipmaps until the end of the texture starting from destinationMip. Arguments that copy invalid slices (e.g. out of range or zero) will lead to an error.

Declaration

public int numMips

Field Value

Type	Description
int

numSlices

The number of slices to blit. -1 to blit all slices until the end of the texture starting from destinationSlice. Arguments that copy invalid slices (e.g. out of range or zero) will lead to an error.

Declaration

public int numSlices

Field Value

Type	Description
int

propertyBlock

The material propery block to use, can be null. The blit functions will modify the sourceTexturePropertyID, sourceSliceProperty, and sourceMipPropertyID of this material poperty block as part of the blit. Calling propertyBlock's SetTexture(...) function used by BlitMaterialParameters should be avoid since it will cause untracked textures when using RenderGraph. This can cause unexpected behaviours.

Declaration

public MaterialPropertyBlock propertyBlock

Field Value

Type	Description
MaterialPropertyBlock

shaderPass

The shader pass index to use.

Declaration

public int shaderPass

Field Value

Type	Description
int

source

The source texture. This texture will be set on the specified material property block property with the name specified sourceTexturePropertyID. If the property block is null, a temp property block will be allocated by the blit function.

Declaration

public TextureHandle source

Field Value

Type	Description
TextureHandle

sourceMip

The first source mipmap to blit from. -1 to ignore source mips and set it to 0 without looping for each destination mip.

Declaration

public int sourceMip

Field Value

Type	Description
int

sourceMipPropertyID

The scalar property to set with the source mip index. If -1 the default "_SourceMip" property will be used. Note: Use Shader.PropertyToID to convert a string property name to an ID. If more than one mip is rendered using the blit function (numMips>1) several full screen quads will be rendered for each slice with different sourceMipPropertyID values set.///

Declaration

Type	Description
int

sourceSlicePropertyID

The scalar property to set with the source slice index. If -1 the default "_SourceSlice" property will be used. Note: Use Shader.PropertyToID to convert a string property name to an ID. If more than one slice is rendered using the blit function (numSlices>1) several full screen quads will be rendered for each slice with different sourceSlicePropertyID values set.

Declaration

public int sourceSlicePropertyID

Field Value

Type	Description
int

sourceTexturePropertyID

The texture property to set with the source texture. If -1 the default "_MainTex" texture property will be used. Note: Use Shader.PropertyToID to convert a string property name to an ID. If propertyBlock is null the texture will be applied directly to the material.
