I hear a lot of people talk about Bryce, and the adverts are all flashy, but I learned a long time ago never to trust adverts. What exactly does Bryce do? Can I create 3D objects in Bryce? People? Landscapes? How easy is it to use? If I'm going to spnd $100 on something, when I have very little $$ to spend on anything, I wanna know it will do exactly what I need it to. Thanks
