Yes, that is correct CrazyDawg. Between the high polys and the textures an aweful amount of space is taken up with these models. Although it can be quite challenging and rewarding to model in Bryce, it can also be quite time consuming and tedious. That's why some people go running to other free 3D modeling programs to import into Bryce for rendering. Who knows, maybe in a future version of Bryce you might be able to do some real modeling.
