Advanced section of the ifmNormalMapping Attribute Editor
Directional Bump
Use this attribute to set the bump depth independent for tangent and bitangent. If this attribute is on the attribute Bump Depth in the General section of the ifmNormalMapping node has no effect.
To connect the ifmNormalMapper you can simply drag and drop the node to the bump map attribute of any Iray for Maya 2.0 material. The basic connection is ifmNormalMapper.outNormal to, for example, ifmOpaque.bump. Because most normal maps are written in sRGB color space Iray for Maya 2.0 connects automatically a gammaCorrect node between the file node and ifmNormalMapping. The default setting for the Gamma attribute for the gammaCorrect node is 2.2, 2.2, 2.2.
