Aye, I recently restructured some parts of this fortress to make it more Bryceable. Originally, all of the windows had physical bars, which were simply cylinders. So, each one had four or five cylinders apiece. Muliplied through, this turned out to be too heavy on polys, the bars themselves having nearly one million polys. So, I did some re-grouping in Rhino, and exported just the FRAMES back into my Bryce scene, and boom! On million less polys, and much more managibility... Now I can actually insert the 600,000 polys worth of torch objects and hopefully get a nice clean render soon...
