Variables

  Type Name Description
Protected variable bool[4] bChannelValid Tracks which of the 4 channels has valid texture data.
Protected variable FVector2D CoordinateBias The bias which is applied to the shadow-map coordinates before sampling the shadow-map textures.
Protected variable FVector2D CoordinateScale The scale which is applied to the shadow-map coordinates before sampling the shadow-map textures.
Protected variable FVector4f InvUniformPenumbraSize Stores the inverse of the penumbra size, normalized.
Protected variable TObjectPtr< UShadowMapTexture2D > Texture The texture which contains the shadow-map data.
