Bryce was my first app together with Vue,i liked them both but i dont use them anymore.bryce is great but the render times are heavy and Vue crashed often on my windows 2000 computer and so i sold it.now im using terragen and mojoworld.if i need very good and realistic skies in carrara then i render them in terragen and use the image as backround in carrara and i can make hdri files in terragen.mojoworld is really cool cause i can make a whole planet. now im thinking about using bryce again and buying vue professional because of the great new features that vue has.
