static

BeginDestroy()

void UMaterialInterface::BeginDestroy ( )

overridevirtual

Called before destroying the object. This is called immediately upon deciding to destroy the object, to allow the object to begin an asynchronous cleanup process.

Reimplemented from UObject.

Reimplemented in UMaterial, and UMaterialInstance.

CacheShaders()

virtual void UMaterialInterface::CacheShaders ( EMaterialShaderPrecompileMode  CompileMode = EMaterialShaderPrecompileMode::Default )

inlinevirtual

Submits remaining shaders for recompilation.

This function will submit any remaining shaders to be compiled for the given material. By default these shader compilation jobs will be compiled in the background.

CompileMode

Controls whether or not we block on the shader compile results.

Reimplemented in UMaterial, and UMaterialInstance.

virtual void UMaterialInterface::DumpDebugInfo ( FOutputDevice &  OutputDevice ) const

inlinevirtual

Reimplemented in UMaterial, and UMaterialInstance.

EnsureIsComplete()

void UMaterialInterface::EnsureIsComplete

(

)

Checks to see if this material has all its shaders cached and if not, will perform a synchronous compilation of those.

Materials are not guaranteed to have all their shaders compiled after loading and using this function before a draw will ensure that the material will not render until it's ready to (and use a fallback material instead). This needs to be avoided in the common render path but can be useful in critical tools (e.g. landscape) that rely on the material and cannot afford a fallback material. In the editor, it will display a toast when waiting for the shaders to compile.

FinishDestroy()

void UMaterialInterface::FinishDestroy ( )

overridevirtual

Called to finish destroying the object. After UObject::FinishDestroy is called, the object's memory should no longer be accessed.

Warning

Because properties are destroyed here, Super::FinishDestroy() should always be called at the end of your child class's FinishDestroy() method, rather than at the beginning.

SubmitRemainingJobsForWorld()

void UMaterialInterface::SubmitRemainingJobsForWorld ( UWorld *  World, EMaterialShaderPrecompileMode  CompileMode = EMaterialShaderPrecompileMode::Default  )

static

Submits shaders to be compiled for all the materials in the world.

This function will submit any remaining shaders to be compiled for all the materials in the passed in world. By default these shader compilation jobs will be compiled in the background so if you need the results immediately you can call FinishAllCompilation() to block on the results.

If the world is nullptr this will submit remaining shaders to be compiled for all the loaded materials.

GShaderCompilingManager->SubmitRemainingJobsForWorld(World);
GShaderCompilingManager->FinishAllCompilation();

Parameters

World	Only compile shaders for materials that are used on primitives in this world.
CompileMode	Controls whether or not we block on the shader compile results.

Note

This will only submit shader compile jobs for missing shaders on each material. Calling this multiple times on the same world will result in a no-op.

virtual class UMaterial* UMaterialInterface::GetMaterial() PURE_VIRTUAL(UMaterialInterface

Get the material which we are instancing. Walks up parent chain and finds the base Material that this is an instance of.

GetMaterial_Concurrent

virtual const class UMaterial* UMaterialInterface::GetMaterial_Concurrent(TMicRecursionGuard RecursionGuard=TMicRecursionGuard()) const PURE_VIRTUAL(UMaterialInterface

Same as above, but can be called concurrently

GetMaterialInheritanceChain

virtual void UMaterialInterface::GetMaterialInheritanceChain(FMaterialInheritanceChain &OutChain) const PURE_VIRTUAL(UMaterialInterface

GetMaterialLayers

virtual bool UMaterialInterface::GetMaterialLayers(FMaterialLayersFunctions &OutLayers, TMicRecursionGuard RecursionGuard=TMicRecursionGuard()) const PURE_VIRTUAL(UMaterialInterface

Get the material layers stack

Returns

- material layers stack, or nullptr if material has no layers

GetNaniteOverride

virtual UMaterialInterface* UMaterialInterface::GetNaniteOverride(TMicRecursionGuard RecursionGuard=TMicRecursionGuard()) const PURE_VIRTUAL(UMaterialInterface

Get the associated nanite override material

Returns

- nanite override, if none was set returns null as a signal to use this material instead

GetParameterInfo

FMaterialParameterInfo UMaterialInterface::GetParameterInfo

GetPhysicalMaterial

virtual UPhysicalMaterial* UMaterialInterface::GetPhysicalMaterial() const PURE_VIRTUAL(UMaterialInterface

Return a pointer to the physical material used by this material instance.

Returns

The physical material.

GetPhysicalMaterialFromMap

virtual UPhysicalMaterial* UMaterialInterface::GetPhysicalMaterialFromMap(int32 Index) const PURE_VIRTUAL(UMaterialInterface

Return a pointer to the physical material from mask map at given index.

Returns

The physical material.

GetPhysicalMaterialMask

virtual UPhysicalMaterialMask* UMaterialInterface::GetPhysicalMaterialMask() const PURE_VIRTUAL(UMaterialInterface

Return a pointer to the physical material mask used by this material instance.

Returns

The physical material.

GetRenderProxy

virtual class FMaterialRenderProxy* UMaterialInterface::GetRenderProxy() const PURE_VIRTUAL(UMaterialInterface

Return a pointer to the FMaterialRenderProxy used for rendering.

Parameters

Selected

specify true to return an alternate material used for rendering this material when part of a selection

Note

: only valid in the editor!

Returns

The resource to use for rendering this material instance.

GetUsedTexturesAndIndices

void UMaterialInterface::GetUsedTexturesAndIndices

final

Return the textures used to render this material.

Parameters

OutTextures	Output of used textures for this material.
InSpecificQualityLevel	If set, only search textures for the given Quality Level, otherwise search for all Quality levels.
InSpecificShaderPlatform	If set, only search textures for the given Shader Platform, otherwise search for all Shader Platforms. Return the textures used to render this material and the material indices bound to each. Because material indices can change for each shader, this is limited to a single platform and quality level. An empty array in OutIndices means the index is undefined.

LightmassSettings

struct FLightmassMaterialInterfaceSettings UMaterialInterface::LightmassSettings

protected

The Lightmass settings for this object.

NeuralProfile

TObjectPtr<class UNeuralProfile> UMaterialInterface::NeuralProfile

Neural network profile. For internal usage, not editable/visible

OnBaseMaterialSetEvent

FOnBaseMaterialIsSet UMaterialInterface::OnBaseMaterialSetEvent

Event triggered when the base material is set

OverrideTexture

virtual void UMaterialInterface::OverrideTexture(const UTexture *InTextureToOverride, UTexture *OverrideTexture, ERHIFeatureLevel::Type InFeatureLevel) PURE_VIRTUAL(UMaterialInterface

Override a specific texture (transient)

Parameters

InTextureToOverride	The texture to override
OverrideTexture	The new texture to use

ParentRefFence

FRenderCommandFence UMaterialInterface::ParentRefFence

A fence to track when the primitive is no longer used as a parent

SetNumericParameterDefault

virtual void UMaterialInterface::SetNumericParameterDefault(EMaterialParameterType Type, const FHashedMaterialParameterInfo &ParameterInfo, const UE::Shader::FValue &Value, EShaderPlatform InShaderPlatform) PURE_VIRTUAL(UMaterialInterface

SpecularProfiles

TArray<TObjectPtr<class USpecularProfile> > UMaterialInterface::SpecularProfiles

Specular Profile. For internal usage, not editable/visible

SubsurfaceProfile

TObjectPtr<class USubsurfaceProfile> UMaterialInterface::SubsurfaceProfile

SubsurfaceProfile, for Screen Space Subsurface Scattering..

SubsurfaceProfiles

TArray<TObjectPtr<class USubsurfaceProfile> > UMaterialInterface::SubsurfaceProfiles

Subsurface Profiles. For internal usage, not editable/visible. For Substrate, there can be many in a material similarly to SpecularProfile (even though only one can be specified per pixel due to the post processing)

TextureStreamingData

TArray<FMaterialTextureInfo> UMaterialInterface::TextureStreamingData

protected

Data used by the texture streaming to know how each texture is sampled by the material. Sorted by names for quick access.
