I was just thinking: What about writing a program that LOOKS like Bryce (layout+features and is able to import br mats and br files) but much more advanced... I've tested Vue 4 and Carrara but no, they've got much to learn about how to make an intuitive interface and you don't feel the "Force". :-) Bryce doesn't evolve via updates but through the enthusiastic users finding new ways to "bend" this brilliant software; the drawback is that we Brycers are spoiled for good. ;-)
