Yes I have found that Vue is much faster to work with than Bryce and a great chunk of the time saved is on test rendering. The interface is another reason for speed with Vue, it really is well designed.It is true about Bryce and the depth and power of its terrain editor compared to Vue.It is such a shame that the future of Bryce is unclear at this time. I really feel for the artists for whom Bryce is their main ap. Vue is worth the money though just for the speed.
