Return Value

The material values include the face color (R,G,B values), reflectivity (ambient, diffuse, specular, shininess), transparency and emission. All values can be from 0 to 1.

This method returns a NULL VARIANT (or an S_false HRESULT for COM implementations) if this face has not been explicitly modified from the material property values of the body. If you create a body and change the body color to red, then IFace2::IGetMaterialPropertyValues2 and IFace2::GetMaterialPropertyValues2 return a NULL array because you did not specifically change the values of the face.

The format of the parameters or return values is an array of doubles as follows:

[ R, G, B, Ambient, Diffuse, Specular, Shininess, Transparency, Emission ]

To reset the face to use the default part material properties, use IModelDoc2::SelectedFaceProperties.

This method does not support faces obtained from reference surface bodies.
