We [as in the whole blender game community] feel so special now! Look at all those features! Not only we can now use materials for our objects, but we can also have all those lighting methods, AND Toon Shading!
(Downloading as I write )
One question, what do Material Ipos do? We can animate the IPOs of a materials colors and alpha and that will be reflected in the game engine?
All these features are excellent!
