Structs

LightmassMaterialInterfaceSettings

Modifiers: native

Material interface settings for Lightmass

float EmissiveBoost

Scales the emissive contribution of this material to static lighting.

float DiffuseBoost

Scales the diffuse contribution of this material to static lighting.

float SpecularBoost

Scales the specular contribution of this material to static lighting.

float ExportResolutionScale

Scales the resolution that this material's attributes were exported at.

This is useful for increasing material resolution when details are needed.

bool bOverrideEmissiveBoost

If TRUE, override the emissive boost setting of the parent material.

bool bOverrideDiffuseBoost

If TRUE, override the diffuse boost setting of the parent material.

bool bOverrideSpecularBoost

If TRUE, override the specular boost setting of the parent material.

bool bOverrideExportResolutionScale

If TRUE, override the export resolution scale setting of the parent material.

Default values:

Property	Value
DiffuseBoost	1.0
EmissiveBoost	1.0
ExportResolutionScale	1.0
SpecularBoost	1.0

Native functions

GetFontParameterValue

native function bool GetFontParameterValue (name ParameterName, out Font OutFontValue, out int OutFontPage)

GetMaterial

native final noexport function Material GetMaterial ()

GetPhysicalMaterial

native final noexport function PhysicalMaterial GetPhysicalMaterial () const

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

Returns:

The physical material.

GetScalarCurveParameterValue

native function bool GetScalarCurveParameterValue (name ParameterName, out Object.InterpCurveFloat OutValue)

GetScalarParameterValue

native function bool GetScalarParameterValue (name ParameterName, out float OutValue)

GetTextureParameterValue

native function bool GetTextureParameterValue (name ParameterName, out Texture OutValue)

GetVectorCurveParameterValue

native function bool GetVectorCurveParameterValue (name ParameterName, out Object.InterpCurveVector OutValue)

GetVectorParameterValue

native function bool GetVectorParameterValue (name ParameterName, out Object.LinearColor OutValue)

SetForceMipLevelsToBeResident

native function SetForceMipLevelsToBeResident (bool OverrideForceMiplevelsToBeResident, bool bForceMiplevelsToBeResidentValue, float ForceDuration)

Forces the streaming system to disregard the normal logic for the specified duration and instead always load all mip-levels for all textures used by this material.

Parameters:

• ForceDuration - Number of seconds to keep all mip-levels in memory, disregarding the normal priority logic.
