Syntax

class UMaterialEditorInstanceConstant : public UObject

Variables

Type	Name	Description
FMaterialInstanceBasePropertyOverrides	BasePropertyOverrides
uint32: 1	bIsFunctionInstanceDirty
uint32: 1	bIsFunctionPreviewMaterial
uint32: 1	bNaniteOverride	When set we will use the override from NaniteOverrideMaterial.
uint32: 1	bOverrideSubsurfaceProfile	Defines if SubsurfaceProfile from tis instance is used or it uses the parent one.
bool	bShowOnlyOverrides	Whether or not we should show only overridden properties
uint32: 1	bUseOldStyleMICEditorGroups	Should we use old style typed arrays for unassigned parameters instead of a None group (new style)?
TWeakPtr< class IDetailsView >	DetailsView
FLightmassParameterizedMaterialSettings	LightmassSettings	The Lightmass override settings for this object.
TObjectPtr< UMaterialInterface >	NaniteOverrideMaterial	An override material which will be used instead of this one when rendering with nanite.
TArray< struct FEditorParameterGroup >	ParameterGroups
TObjectPtr< class UMaterialInterface >	Parent	Since the Parent may point across levels and the property editor needs to import this text, it must be marked lazy so it doesn't set itself to NULL in FindImportedObject
TObjectPtr< class UPhysicalMaterial >	PhysMaterial	Physical material to use for this graphics material. Used for sounds, effects etc.
float	RefractionDepthBias	This is the refraction depth bias, larger values offset distortion to prevent closer objects from rendering into the distorted surface at acute viewing angles but increases the disconnect between surface and where the refraction starts.
TObjectPtr< class UMaterialFunctionInstance >	SourceFunction
TObjectPtr< class UMaterialInstanceConstant >	SourceInstance
TArray< TObjectPtr< class UMaterialInstanceConstant > >	StoredBlendPreviews
TArray< TObjectPtr< class UMaterialInstanceConstant > >	StoredLayerPreviews
TObjectPtr< class USubsurfaceProfile >	SubsurfaceProfile	SubsurfaceProfile, for Screen Space Subsurface Scattering
TArray< FMaterialParameterInfo >	VisibleExpressions
