Aye, Lightning is really easy, once you get the hang of it. Stills are weird, you have to render "zero" frames! But I almost never render on just one machine, anymore, except when I'm building a scene. Final images get done ina flash, and the "tile" renderer is a bit cooler than the "slow-moving-laser" renderer... Also, with as many computers as you are using, you have a chance to really dig into the animation aspects of Bryce, which is why 3D was invented in the first place!
