AFAIK, when 3DS Max exports objects it collapses them to the highest level. So when you load in your model, it only has 1 unwrap map. This is, of course, assuming the model is one object rather than mutiple objects. If it IS multiple objects, then load in your mesh with LoadAnimMesh.
That will retain heirarchy so you can iterate through the child entities and texture them individually. Use EntityName to get their MAX object names.
