Off the top of my head, Blitz supports multitexturing - use the texture 'index' number of whatever it is called to assign which layer the texture goes too.
Proabaly best to load each texture into a blitz 'Brush' then set its FX properties using the other brush commands then apply the brush to the model (specifiying which texture layer somewhere in all that - sorry, cant remember the commands off hand).
You must apply the same FX to each brush/texture, so you may need three textures for your model. This might also mean you need to split the model into several surfaces or meshes so you can apply the correct texture to each location.
