Quote - Yeah, sure enough, it doesn't work... only saves the pose of one of the figures you select in the "Select Subset" box.

Certainly, I've always used the parented figures saved to a cr2, or the Scene Library option my before... guess that's why :)

How would poser know which figures to apply the pose to?

I think that is the main reason. And if you would use named or use sequence numbers, it is going to get pretty difficult to manage
