References

Module	DynamicMesh
Header	/Engine/Plugins/Experimental/GeometryProcessing/Source/DynamicMesh/Public/DynamicMeshAttributeSet.h
Include	#include "DynamicMeshAttributeSet.h"

Syntax

class FDynamicMeshAttributeSet : public TDynamicAttributeSetBase< FDynamicMesh3 >

Remarks

FDynamicMeshAttributeSet manages a set of extended attributes for a FDynamicMesh3. This includes UV and Normal overlays, etc.

Currently the default is to always have one UV layer and one Normal layer
