Listen I usually dont answer these things but I think that if you are going to do it,it should be 100% Bryce and only that what comes with the cd's from Bryce should be used...That means the content cd from Bryce has tons of extra stuff that comes with Bryce pics and models There is enough there to be able to model a scene...also what about folks who have just 4 or even 3 The metaballer kind of throws them into a disdavantage right at the beggining,so I suggest different catagories for bryce then,1st one should be 100% Bryce,the second of course would allow postwork and imports,This is a way that could accomodate all Brycers...Just a thought and hey guys what about my Effects can I use them?
