Public Member Functions
	ScannedMaterialParams ()
	sss thickness multiplier

Public Attributes
float	bumpmul
	not used

float	bumpstart
	bump multiplier for the inclined views

int	BWforGI
	Used in volumetric translucency calculation, switches between two models of calculation, fast(1) and sss(0)

float	ccbump
	clear coat highlights

float	ccglossy
	The material is represented as non colored for the GI rays, used to prevent the color bleeding when the color will be replaced in post.

float	ccglossyvar
	Clear coat glossiness, the measured value is kept in presets.specbell.

int	cchlight
	the clear coat ior, used for carpaints and other materials with thin refractive layer

float	ccior
	the size of one scene unit in cm

float	ccmetalrefl
	rendering without using the GI engine at all (but most scenes have low scanned materials in count)

float	ccmul
	This parameter modifies the clear coat reflection to metalic behavior, i.e., it modulates the reflection color by the underlying BRDF color.

ColorSpace	clrSpace
	strength of the filter

float	cutoff
	the reflection rays count, the UI contains subdivision parameter, this must be seto to the square value of the subdivisions (Not used anymore)

float	depthMul

int	disablewmap
	displacement/paralax multiplier

int	displace
	same as two side in the standard material

int	dome
	the mapping channel

int	fasttrans
	Controls the triplanar mapping, combination of enum Triplanar flags.

Color	filter
	disable use of the enlargement, directly the original small sample is used for rendering (Not used anymore, potentialy bug causing option)

float	fltStrength
	strength of the replace paint effect

float	invgamma
	this option modifies the rendering in order to improve the result for materials without large details

int	mapChannel
	stop of the indirect ray if the total weight is below this value

MapChannelsMask	mapChBitmask
	multiplies the transparency (only the transparency, the translucency remains!) (Not used anymore)

float	multdirect
	prevent double lighting by direct and reflection rays (not used anymore)

float	multgi

float	multrefl

Bool	noCachedGI
	the output color space (Not used anymore, replaced by the vray color space)

int	noPrimGI
	edge displacement, used to prevent the flat appearance of the edges

int	noTransp
	the minimal path length of a reflected ray that allows to use GI, if the path is shorter "fear" ray tracing is used (Not used anymore)

int	nsamples
	the z value of the view vector below which bump is gradualy applied

float	paintStrength
	bitmask for the maps used in the rendering

Plain	plain

float	retrace
	the primary rays are rendered without using the GI engine (better acuracity, lower speed) (Not used anymore)

float	saturation
	inverse gamma

float	sceneScale
	used when the plain option is set to PL_SCRAMBLE, determines the size of the pieces that are continuous in the uv space , measured in cm (Not used anymore)

float	scrambleSize
	limit for the tracing recursion

float	sssmul
	Clear coat glossiness variation, the measured value is kept in presets.scratchdens.

int	traceDepth
	multipliers for different parts of the light (not used anymore)

float	transpMul
	force opaque rendering even if backside lighting is present.

int	triplanar
	Clear coat multiplier.

int	twoside
	uniform reflections distribution, when nonzero the importance sampling is not used

int	unfRefl
	used to make the clear coat not perfect

int	usemap
	uv mapping transformation matrix

Transform	uvtrans
	general result multiplier (tint)
