Syntax

class UMaterialExpressionLandscapePhysicalMaterialOutput : public UMaterialExpressionCustomOutput

Remarks

Custom output node to write out physical material weights. This can be used to generate the dominant physical material for each point on a landscape.

that the use of a material output node to generate this information is optional and when a node of this type is not present we fall back on a CPU path which analyzes landscape layer data.
