shiuld be LW 7.0 or 7.5, 6.0 or 6.5 doesn't work as the older version do not keep g info but mtl. back in lw 6.5 when i used it to model or modify poser geometries, it was a bit harsh as the old verson just ignored group info, so i had to figure out the workaround to trandfer the g info back to poser. thanks anyway.
