Oh... actually, just thinking about the way that Bryce renders things, that makes sense. Nevetheless, it still needs it. And I think that the raytracing could possibly be used to calculate polygon positions and rotations. Not sure about that, I don't know much about raytracing in practicality (I just know how it works in theory). Don't give up the program. Just don't upgrade. Personally, if they add dynamics, I'll still upgrade. By they better have better modeling abilities in v6, you're right.
