About multi texture take a look at TextureUnitState, TextureAttributes, TextureUnitState.setTextureAttribute(TextureAttributes textureAttributes) and Appearance.setTextureUnitState(TextureUnitState[] stateArray),
you can mix several textures using above classes and methods. But there is a hardware limitation on using texture unit state (TU). Old cards (GeForce 2, GF 4MX) can handle up 2 T.U., while GF-4 Ti, FX 5200, etc can handle up to 4 TUs, and ultimate vcards can handle 8 or more TUs (ATi 9800, GF6600, etc). Check your hardware textureUnitStateMax capability running QueryProperties demo. You can mix textures using one of the several modes available in TextureAttributes (modulate, blend, combine, etc). Texture images with Alpha Channel (or transparency mask), as PNG, are very interesting for multitexture. But you need a good image editor to create and edit alpha channel, as GIMP (free), Jasc Paint Shop Pro, PhotoShop, etc. Have fun !
