◆ ClearMaterialAssetId()

virtual void AZ::Render::MaterialComponentRequests::ClearMaterialAssetId ( const MaterialAssignmentId & materialAssignmentId )

pure virtual

Removes the material asset associated with the material assignment ID

Parameters

materialAssignmentId ID of material slot.

◆ ClearMaterialsOnInvalidSlots()

virtual void AZ::Render::MaterialComponentRequests::ClearMaterialsOnInvalidSlots ( )

pure virtual

Clear all material overrides from the material component mapped to material assignment IDs that do not match the current material layout. This is usually used for clearing materials leftover between model changes or moving the material component from one entity to another.

◆ ClearPropertyValue()

virtual void AZ::Render::MaterialComponentRequests::ClearPropertyValue	(	const MaterialAssignmentId &	materialAssignmentId,
		const AZStd::string &	propertyName
	)

pure virtual

Clear any property override associated with the material assignment ID and property name.

Parameters

materialAssignmentId	ID of material slot.
propertyName	Name of the property being cleared.

◆ ClearPropertyValues()

virtual void AZ::Render::MaterialComponentRequests::ClearPropertyValues ( const MaterialAssignmentId & materialAssignmentId )

pure virtual

Clear all property overrides associated with the material assignment ID.

Parameters

materialAssignmentId ID of material slot.

◆ FindMaterialAssignmentId()

virtual MaterialAssignmentId AZ::Render::MaterialComponentRequests::FindMaterialAssignmentId	(	const MaterialAssignmentLodIndex	lod,
		const AZStd::string &	label
	)		const

pure virtual

Search for a material assignment ID matching the lod and label parameters

Parameters

lod	Index of the LOD to be searched for the material assignment ID. -1 is used to search the default material and model material slots.
label	Substring used to look up a material assignment ID with a matching label.

Returns: The corresponding material assignment ID is found, otherwise DefaultMaterialAssignmentId.

◆ GetDefaultMaterialAssetId()

virtual AZ::Data::AssetId AZ::Render::MaterialComponentRequests::GetDefaultMaterialAssetId ( const MaterialAssignmentId & materialAssignmentId ) const

pure virtual

Get the material asset associated with the source model or object prior to overrides being applied.

Parameters

materialAssignmentId ID of material assignment slot for which the information is being requested.

Returns: Default asset ID associated with the material assignment ID, otherwise an invalid asset ID.

◆ GetMaterialAssetId()

virtual AZ::Data::AssetId AZ::Render::MaterialComponentRequests::GetMaterialAssetId ( const MaterialAssignmentId & materialAssignmentId ) const

pure virtual

Retrieve the material asset associated with the material assignment ID

Parameters

materialAssignmentId ID of material slot.

Returns: The current material asset ID is found, otherwise invalid asset ID .

◆ GetMaterialLabel()

virtual AZStd::string AZ::Render::MaterialComponentRequests::GetMaterialLabel ( const MaterialAssignmentId & materialAssignmentId ) const

pure virtual

Get the material asset associated with the source model or object prior to overrides being applied.

Parameters

materialAssignmentId ID of material assignment slot for which the information is being requested.

Returns: String corresponding to the display name of the material slot.

◆ GetMaterialMap()

virtual const MaterialAssignmentMap & AZ::Render::MaterialComponentRequests::GetMaterialMap ( ) const

pure virtual

Returns all materials and properties used by the material component.

Returns: Map of material assigned data including materials, property overrides, and other parameters.

◆ GetModelUvOverrides()

virtual AZ::RPI::MaterialModelUvOverrideMap AZ::Render::MaterialComponentRequests::GetModelUvOverrides ( const MaterialAssignmentId & materialAssignmentId ) const

pure virtual

Get Model UV overrides for a specific material assignment

Parameters

materialAssignmentId ID of material slot.

Returns: Map of remapped UV channels.

◆ GetPropertyValue()

virtual AZStd::any AZ::Render::MaterialComponentRequests::GetPropertyValue	(	const MaterialAssignmentId &	materialAssignmentId,
		const AZStd::string &	propertyName
	)		const

pure virtual

Get the current value of a material property wrapped by an AZStd::any

Parameters

materialAssignmentId	ID of material slot.
propertyName	Name of the property being requested.

Returns: Value of the property is located, otherwise an empty AZStd::any.

◆ GetPropertyValues()

virtual MaterialPropertyOverrideMap AZ::Render::MaterialComponentRequests::GetPropertyValues ( const MaterialAssignmentId & materialAssignmentId ) const

pure virtual

Retrieves a map of all property values associated with the material assignment ID.

Parameters

materialAssignmentId ID of material slot.

Returns: Map of all property values.

◆ IsMaterialAssetIdOverridden()

virtual bool AZ::Render::MaterialComponentRequests::IsMaterialAssetIdOverridden ( const MaterialAssignmentId & materialAssignmentId ) const

pure virtual

Check if the material slot contains an explicit material asset override

Parameters

materialAssignmentId ID of material slot.

Returns: true if a valid material asset has been assigned.

◆ RepairMaterialsWithMissingAssets()

virtual void AZ::Render::MaterialComponentRequests::RepairMaterialsWithMissingAssets ( )

pure virtual

Updates all material overrides referencing material assets that can't be located to instead point to a default material asset.

◆ RepairMaterialsWithRenamedProperties()

virtual uint32_t AZ::Render::MaterialComponentRequests::RepairMaterialsWithRenamedProperties ( )

pure virtual

Remaps material property overrides that have been renamed since they were assigned.

Returns: the number of properties that were updated

◆ SetMaterialAssetId()

virtual void AZ::Render::MaterialComponentRequests::SetMaterialAssetId	(	const MaterialAssignmentId &	materialAssignmentId,
		const AZ::Data::AssetId &	materialAssetId
	)

pure virtual

Assign a material asset to the slot corresponding to material assignment ID

Parameters

materialAssignmentId	ID of material slot that the material will be assigned to.
materialAssetId	Material asset that will be assigned to the material slot.

◆ SetMaterialAssetIdOnDefaultSlot()

virtual void AZ::Render::MaterialComponentRequests::SetMaterialAssetIdOnDefaultSlot ( const AZ::Data::AssetId & materialAssetId )

pure virtual

Convenience function to set the overridden material asset on the default material slot.

Parameters

materialAssetId Material asset that will be assigned to the default material slot.
