Property Value

Array of doubles describing the material values on this face (see Remarks)

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 see a color change, you must:

1. Specify R, G, and B, each with a value between 0.0 and 1.0, inclusive. (These values are internally multiplied by 255.0 to determine the RGB color.)
2. Specify the reflectivity properties (Diffuse, Specular, Shininess (1.0 - Specular spread/Blurriness)), each with a value greater than 0.0 and less than or equal to 1.0.
3. Specify Ambient, Transparency and Emission, each with a value between 0.0 and 1.0, inclusive.
4. Refresh the graphics area after setting this property.

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.
