Name	Remarks
EPrimaryGroupMode	Various modes can be used to create output triangle groups

Name	Type	Remarks	Include Path
bCalculateMaps	bool	Should we calculate conversion index maps	MeshDescriptionToDynamicMesh.h
bDisableAttributes	bool	Ignore all mesh attributes (e.g. UV/Normal layers, color layer, material groups)	MeshDescriptionToDynamicMesh.h
bEnableOutputGroups	bool	Should we initialize triangle groups on output mesh	MeshDescriptionToDynamicMesh.h
