What are some programs that can do what Bryce 4/5 do AND have an easy UI like all of Metacreations' software does (did)? I love Bryce, but I don't like some of its limitations (e.g. only has primitives). Another feature would have to be a price below $500 (It's only a hobby). I generally make scenes, but some I also do some object modeling when I need to. Thanks!
