class UMaterialExpressionStrataSingleLayerWaterBSDF : public UMaterialExpressionStrataBSDF

Type	Name	Description
FExpressionInput	BaseColor	Surface base color. (type = float3, unit = unitless, defaults to black)
FExpressionInput	ColorScaleBehindWater	A scale to apply on the scene color behind the water surface.
FExpressionInput	EmissiveColor	Emissive color on top of the surface (type = float3, unit = luminance, defaults to 0.0)
FExpressionInput	Metallic	Whether the surface represents a dielectric (such as plastic) or a conductor (such as metal).
FExpressionInput	Normal	The normal of the surface (type = float3, unit = unitless, defaults to +Z vector)
FExpressionInput	Roughness	Controls how rough the Material is.
FExpressionInput	Specular	Specular amount (type = float, unit = unitless, defaults to 0.5)
FExpressionInput	TopMaterialOpacity	Opacity of the material layered on top of the water (type = float3, unit = unitless, defaults to 0.0)
FExpressionInput	WaterAlbedo	The single scattering Albedo defining the overall color of the Material (type = float3, unit = unitless, default = 0)
FExpressionInput	WaterExtinction	The rate at which light is absorbed or out-scattered by the medium.
FExpressionInput	WaterPhaseG	Anisotropy of the volume with values lower than 0 representing back-scattering, equal 0 representing isotropic scattering and greater than 0 representing forward scattering.

Type	Name	Description
int32	Compile ( FMaterialCompiler* Compiler, int32 OutputIndex )	Create the new shader code chunk needed for the Abs expression
void	GatherStrataMaterialInfo ( FStrataMaterialInfo& StrataMaterialInfo, int32 OutputIndex )	Recursively parse nodes outputing strata material in order to gather all the possible shading models used in a material graph output a Strata material.
void	GetCaption ( TArray< FString >& OutCaptions )	Returns the text to display on the material expression (in the material editor).
uint32	GetInputType ( int32 InputIndex )
uint32	GetOutputType ( int32 OutputIndex )
bool	IsResultStrataMaterial ( int32 OutputIndex )	Marks certain expression types as outputting Strata material.
FStrataOperator *	StrataGenerateMaterialTopologyTree ( FMaterialCompiler* Compiler, UMaterialExpression* Parent, int32 OutputIndex )	A starta material is a tree with FrontMateiral being its root and BSDF being leaves, with operators in the middle.
