Dynamics simulation would be neat :) but I would settle for radiosity, caustics, and a good bone system. Actually what would be really cool would be if they could just take the modelling aspect of 3ds max and put it together with the render engine of lightwave. That would make me a happy panda. Oh, and don't forget backgound images and maybe lots of different color schemes...and the ability of rendering nicely lit wireframes rather than using the zbuffer. Oh...and don't change the meatballs. Jared
