CropUnmappedTexels()

template<class TMappingData >

void CropUnmappedTexels	(	const TMappingData &	MappingData,
		int32	SizeX,
		int32	SizeY,
		FIntRect &	CroppedRect
	)

Calculates the minimum rectangle that encompasses all mapped texels.

Parameters

MappingData	Array of lightmap/shadowmap texels
SizeX	Number of texels along the X-axis
SizeY	Number of texels along the Y-axis
CroppedRect	[out] Upon return, contains the minimum rectangle that encompasses all mapped texels

IsTexelDebuggingEnabled()

ENGINE_API bool IsTexelDebuggingEnabled ( )

extern

IsTexelMapped()

bool IsTexelMapped ( const TArray< FLightMapCoefficients > &  MappingData, int32  X, int32  Y, int32  Pitch  )

inline

Checks if a lightmap texel is mapped or not.

Parameters

MappingData	Array of lightmap texels
X	X-coordinate for the texel to check
Y	Y-coordinate for the texel to check
Pitch	Number of texels per row

Returns

true if the texel is mapped

operator<<()
