group names for poser from zbrush

[outland86]

Hi all newbie here

i am trying to export a model from zbrush to poser and have done that but
when it comes into poser the parts are grouped with names that Zbrush auto creates eg group13256......group23456 etc etc

my question is how do i change the names assigned to each part in zbrush before i export as obj file so that they appear in poser with the group names i want...instead of Zbrushes auto names


hope this make sense to someone

thanks in advance
