Thanks for replying, oilscum. I opened up one of the INJ pose files, it was very compact and there were no unnecessary references i.e. there was a 1:1 correspondence between the readScript calls and the segments under actor:head. FWIW, there was also an embedded comment saying that it had been created by Injection Magic. Having said all this, it still didn't want to work unless I first loaded up the head morphs. I found this out by trial and error - if I tried to load up the pose without loading up the head morphs, the Poser session would hang - but if I loaded up the head morphs first and then applied the Pose, it would work. regards, Andrew
