15.2 ifmNormalMapping
Iray for Maya 2.0 handles normal maps different than Maya. In Maya the normal map can be used by switching the attribute Use As: in the bump2d node to Tangent SpaceNormals or Object Space Normals. Unfortunately this mechanism does not work for Iray for Maya 2.0. To take advantage of normal maps with Iray for Maya 2.0 the ifmNormalMapping node is introduced.
