Someone sent me a URL with some info on Worldcraft 3.3, and I maintain that Tread3D2 is better. I customized some colors and undocked the interface to show you just how versatile Tread3D2 is. This entire Quake2 level pans at about 10 f.p.s on my Viper 770 TNT/2. Definently good enough to edit it. Oh, and yeah, that's transparent water.
