thanks miss nancy for your reply .

i suggest for this problem to : import bvh on the figure in poser first. drop to floor on all animation. and export in ...bvh . secondly, reimport in C6pro. that should work ! maybe ?

but could you tell me please how to " drop figure on floor in all frames" in poser 7 ? that looks very helpful. where could i find this script ?

thanks again miss nancy. hope my suggestion could help you too :)
