Accessing Textures

I am working with a model that was made in 3ds max that has many different textures applied to one model. When everthing is converted to an egg Panda sees that there are 5 textures on one node. I want to be able to change textures with the press of a button in the code so I can change different parts of a characters outfit. How can I access these geometries so I can change the textures? The hierarchy of the model looks like this
ModelNode Male
ModelNode actorGeom
Character __Actor_modelRoot
GeomNode body (5 geoms: TextureAttrib)
GeomNode theHat (1 geoms: TextureAttrib Transparency Attrib)

You need to flag the different pieces so you can access them individually. See this page of the manual.
