Function Documentation

CanIndirectLightingCacheUseVolumeTexture()

bool CanIndirectLightingCacheUseVolumeTexture

(

ERHIFeatureLevel::Type

InFeatureLevel

)

Returns true if the indirect lighting cache can use the volume texture atlas on this feature level.

IsIndirectLightingCacheAllowed()

bool IsIndirectLightingCacheAllowed

(

ERHIFeatureLevel::Type

InFeatureLevel

)

Returns true if the indirect lighting cache can be used at all.

Variable Documentation

BoundSizeRoundUpBase

const float BoundSizeRoundUpBase = FMath::Sqrt(2.f)

Primitive bounds size will be rounded up to the next value of Pow(BoundSizeRoundUpBase, N) and N is an integer. This provides some stability as bounds get larger and smaller, although by adding some waste.
