Here are some file details and other info. I ran the skeleton march today again with 45 skeletons (the one on the site has 20 bonemen). I also added some volume fog. I'll post the mpg later. Total render time 8 hour (1Ghz 256Mb upgraded Dell computer). Bryce 4 file size 16.9 kb. Poser exported OBJ files (25) total size 35MB. 150 resulting uncompressed BMP files 33.1MB Total uncompressed size for everything included about 69 MB. Using materials does not add much a few kb here and there: same material can be used for many objects. About a MAC version. I regret to say that the s/w code is pretty much windows specific and hard to port. Next thing coming is a Bryce 5 port and perhaps a Vue port.
