If they were modelled in verson 6 of C4D which is the one that went out on a cover CD some time ago,or with the Eclectic Academy course I took then that version doesn't have any group facility. May be that the modeller won't even have a way of correcting it. That said though, I made things in my version 6 before I upgraded and they imported to bryce 5.01 fine, even if they did get some very bizarre mesh names. Kathy
