I think it's interesting not for conversion puposes but that you could write little utilities to modify bryce scenes, almost like plugins. For example, you could spawn a light with a given intensity at a specific location and a color related to the nearby object to give a fake radiosity effect, for each object in the scene based on current light sources, without having to do anything manually, which would be tedious positioning and modification of many small light sources. You could also generate textures, improve the terrain lab, etc. I've used many of the "big dog" apps rather intensively, and I keep coming back to bryce because it has a certain flair that the other applications lack...maybe bryce is just more fun? Other apps arealways a bit awkward with the exception of a few like wings, which I use as my main modeler along with bryce for my renderer. Carrara is very bryce-like and has oodles more features and a fantastic renderer, but scene placement is so difficult and counter-productive that I hesitate to open the program. If someone could give carrara the naigation tools in bryce, I'd be much more keen on using it.
