FadeDistance	FExpressionInput	World space distance over which the fade should take place.	Materials/MaterialExpressionDepthFade.h	Meta=(RequiredInput="false", ToolTip="Defaults to 'FadeDistanceDefault' if not specified")
FadeDistanceDefault	float	World space distance over which the fade should take place.	Materials/MaterialExpressionDepthFade.h	EditAnywhere Category=MaterialExpressionDepthFade Meta=(OverridingInputProperty="FadeDistance")
InOpacity	FExpressionInput	Input opacity which will be scaled by the result of the fade.	Materials/MaterialExpressionDepthFade.h	Meta=(RequiredInput="false", ToolTip="Defaults to 'OpacityDefault' if not specified")
OpacityDefault	float	Opacity which will be scaled by the result of the fade. This is used when InOpacity is unconnected.	Materials/MaterialExpressionDepthFade.h	EditAnywhere Category=MaterialExpressionDepthFade Meta=(OverridingInputProperty="InOpacity")
