I may use Carrara as my main renderer, but I still find Bryce to be an indispensable part of my kit. The terrain/ lattice lab in Bryce is much easier to use for manipulating terrains IMO, especially when you know the "Easter Egg" terrain painting tricks. I built a bridge model in a "heretical app", and rendered it in Carrara, but the terrain was totally prepared using Bryce's excellent terrain editor.
