The differences between the two free versions and the comercial ones is that the free ones are for like 3DS DOS and 3DSMax 1.
You can easily create a falloff map in Max to do cellshading.
Kreshi, you're an idiot. The best cell shading is not in Lightwave and Max, it's cabable in most 3D rendering packages, usually just as well as anyother if you know what you're doing.
