Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere FMaterialInstanceBasePropertyOverrides BasePropertyOverrides  
Public variable UProperty Transient duplicatetransient uint32: 1 bIsFunctionInstanceDirty  
Public variable UProperty Transient duplicatetransient uint32: 1 bIsFunctionPreviewMaterial  
Public variable UProperty Category, EditAnywhere, Meta uint32: 1 bNaniteOverride When set we will use the override from NaniteOverrideMaterial.
Public variable UProperty Category, EditAnywhere uint32: 1 bOverrideSubsurfaceProfile Defines if SubsurfaceProfile from tis instance is used or it uses the parent one.
Public variable bool bShowOnlyOverrides Whether or not we should show only overridden properties
Public variable UProperty Category, EditAnywhere uint32: 1 bUseOldStyleMICEditorGroups Should we use old style typed arrays for unassigned parameters instead of a None group (new style)?
Public variable TWeakPtr< class IDetailsView > DetailsView  
Public variable UProperty Category, EditAnywhere FLightmassParameterizedMaterialSettings LightmassSettings The Lightmass override settings for this object.
Public variable UProperty Category, EditAnywhere, Meta TObjectPtr< UMaterialInterface > NaniteOverrideMaterial An override material which will be used instead of this one when rendering with nanite.
Public variable UProperty Category, EditAnywhere editfixedsize TArray< struct FEditorParameterGroup > ParameterGroups  
Public variable UProperty Category, EditAnywhere, Meta 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
Public variable UProperty Category, EditAnywhere TObjectPtr< class UPhysicalMaterial > PhysMaterial Physical material to use for this graphics material. Used for sounds, effects etc.
Public variable UProperty Category, EditAnywhere FMaterialEditorPostProcessOverrides PostProcessOverrides Overrides specific to Post Process domain materials.
Public variable UProperty Category, EditAnywhere 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.
Public variable UProperty TObjectPtr< class UMaterialFunctionInstance > SourceFunction  
Public variable UProperty TObjectPtr< class UMaterialInstanceConstant > SourceInstance  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadOnly TObjectPtr< class USubsurfaceProfile > SubsurfaceProfile SubsurfaceProfile, for Screen Space Subsurface Scattering
Public variable UProperty Transient duplicatetransient TArray< FMaterialParameterInfo > VisibleExpressions
