Hi Black cat, Well that's exciting. It may be coming down to some system stuff. How much installed RAM do you have? I've worked with files up to 800M but it hasn't been with Poser content. I do know that conforming clothing and memory usage is continuing to be improved in Carrara and is a big priority. Conforming clothing often has more polys than the actual figures they cover. While that might not create super massive files, it seems that tracking a bunch of polys that are linked to other polys regarding there positioning is where the memory management issues may come in. So, until that improvement takes place, this may be your excuse to buy more RAM if you don't have several Gigs installed. ;-) Mark
