Bitmasks used to set and access the :c:member:`A3DTessFaceData::m_usUsedEntitiesFlags <A3DTessFaceData.m_usUsedEntitiesFlags>`\ .


   2.0


If this flag is set, the corresponding OneNormal entity (see :ref:`Bitmasks for Specifying Tessellation Types <group__a3d__tessfacetype>`\ ) is planar and only one normal is defined for the entity. Otherwise, one normal per point is defined.
