Default color – The color that is returned if the specified user property cannot be found on the currently shaded object.
Default texmap – Specifies a texture to be used for the default color if the user property cannot be found on the currently shaded object.
Attribute name – A string that specifies the name of the User-Defined property.
The text box below the parameters shows the possible formats for the value of the user-defined property. Suppose that we want to take the texture color from a user property named diffuse_color. Then if we want to specify red color on one object, we could specify this as diffuse_color=1,0,0 and if we want green color on another object, we could specify this as diffuse_color=0,1,0
