Bryce can make most things. But it does not have deformers or any of the more advanced modeling tools.
With clever use you can get really complex shapes. However if you have specific goals or are impatient, it is faster in other modelers.
Here is an object made entirely out of booleans. I originally made it in Bryce, I later re-made it (using the same exact techniques) in Truespace. Mostly to see how Truespace’s modeler stacked up against others I owned (Lightwave, C4d)
If you want to DL the model to play with it, it is free at:
btw: how do you link to an external image now? I tried the img tag but it did not work.
